* zswap: runtime enable/disableDan Streetman2015-06-251-2/+16
| | | | | | | | | | | | | | | | Change the "enabled" parameter to be configurable at runtime. Remove the enabled check from init(), and move it to the frontswap store() function; when enabled, pages will be stored, and when disabled, pages won't be stored. This is almost identical to Seth's patch from 2 years ago: http://lkml.iu.edu/hypermail/linux/kernel/1307.2/04289.html [akpm@linux-foundation.org: tweak documentation] Signed-off-by: Dan Streetman <ddstreet@ieee.org> Suggested-by: Seth Jennings <sjennings@variantweb.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* zram: add dynamic device add/remove functionalitySergey Senozhatsky2015-06-252-3/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently don't support on-demand device creation. The one and only way to have N zram devices is to specify num_devices module parameter (default value: 1). IOW if, for some reason, at some point, user wants to have N + 1 devies he/she must umount all the existing devices, unload the module, load the module passing num_devices equals to N + 1. And do this again, if needed. This patch introduces zram control sysfs class, which has two sysfs attrs: - hot_add -- add a new zram device - hot_remove -- remove a specific (device_id) zram device hot_add sysfs attr is read-only and has only automatic device id assignment mode (as requested by Minchan Kim). read operation performed on this attr creates a new zram device and returns back its device_id or error status. Usage example: # add a new specific zram device cat /sys/class/zram-control/hot_add 2 # remove a specific zram device echo 4 > /sys/class/zram-control/hot_remove Returning zram_add() error code back to user (-ENOMEM in this case) cat /sys/class/zram-control/hot_add cat: /sys/class/zram-control/hot_add: Cannot allocate memory NOTE, there might be users who already depend on the fact that at least zram0 device gets always created by zram_init(). Preserve this behavior.

* zram: remove max_num_devices limitationSergey Senozhatsky2015-06-251-1/+3
| | | | | | | | | | | Limiting the number of zram devices to 32 (default max_num_devices value) is confusing, let's drop it. A user with 2TB or 4TB of RAM, for example, can request as many devices as he can handle.

| * Documentation/vm/unevictable-lru.txt: clarify MAP_LOCKED behaviorMichal Hocko2015-06-241-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a very subtle difference between mmap()+mlock() vs mmap(MAP_LOCKED) semantic. The former one fails if the population of the area fails while the later one doesn't. This basically means that mmap(MAPLOCKED) areas might see major fault after mmap syscall returns which is not the case for mlock. mmap man page has already been altered but Documentation/vm/unevictable-lru.txt deserves a clarification as well.

| * watchdog: add watchdog_cpumask sysctl to assist nohzChris Metcalf2015-06-242-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the default behavior of watchdog so it only runs on the housekeeping cores when nohz_full is enabled at build and boot time. Allow modifying the set of cores the watchdog is currently running on with a new kernel.watchdog_cpumask sysctl. In the current system, the watchdog subsystem runs a periodic timer that schedules the watchdog kthread to run. However, nohz_full cores are designed to allow userspace application code running on those cores to have 100% access to the CPU. So the watchdog system prevents the nohz_full application code from being able to run the way it wants to, thus the motivation to suppress the watchdog on nohz_full cores, which this patchset provides by default. However, if we disable the watchdog globally, then the housekeeping cores can't benefit from the watchdog functionality. So we allow disabling it only on some cores. See Documentation/lockup-watchdogs.txt for more information.

In practice these days though we have some maintainers taking on preferences to require all new functionality go in with EXPORT_SYMBOL_GPL(). A maintainer asking developers to use EXPORT_SYMBOL_GPL() for new functionality tends to be a well accepted and understood position that maintainers can take and typically requires the maintainers educating contributing developers on their own positions and requirements. Developers who submit code to maintainers not familiar with these preferences as optional for new functionality need explicit guidence though as existing documentation does not acknowledge this as a valid possibility. Without this being documented some maintainers are reluctant to accept new functionality with EXPORT_SYMBOL_GPL(). This extends the use case documentation for EXPORT_SYMBOL_GPL() to acknowledge acceptance for new functionality. Signed-off-by: Luis R.

The parameters vendor= and product= have been superseded by a /sys interface.

Changes relative to the last submission: - Added higher level subsystem directories to collect features by subsystem: triton:~/tip> ls Documentation/features/ arch-support.txt core debug io lib list-arch.sh locking perf sched seccomp time vm each subsystem directory contains the feature directories. For example locking has: triton:~/tip> ls Documentation/features/locking/ cmpxchg-local lockdep queued-rwlocks queued-spinlocks rwsem-optimized It's all pretty straightforward to navigate. Advantages are better visualization, plus git log is able to list changes per subsystem. - Prettified the visualization some more. - Improved/corrected the support matrices based on feedback to earlier submissions. - Updated the support matrices to today's linux-next, so that by the time this shows up in upstream in the next merge window it's really recent. Most notably there's a new architecture in linux-next (h8300). This structure should address all feedback that I got and should minimize the maintenance overhead (chance of conflicts).

The structure of the feature descriptions is the following: Each feature has its own directory under Documentation/features/subsystem_name/feature_name/, and the arch-support.txt file shows its current arch porting status. For example, lockdep support is shown the following way: triton:~/tip> cat Documentation/features/locking/lockdep/arch-support.txt # # Feature name: lockdep # Kconfig: LOCKDEP_SUPPORT # description: arch supports the runtime locking correctness debug facility # ----------------------- | arch |status| ----------------------- | alpha: | TODO | | arc: | ok | | arm: | ok | | arm64: | ok | | avr32: | ok | | blackfin: | ok | | c6x: | TODO | | cris: | TODO | | frv: | TODO | | h8300: | TODO | | hexagon: | ok | | ia64: | TODO | | m32r: | TODO | | m68k: | TODO | | metag: | ok | | microblaze: | ok | | mips: | ok | | mn10300: | TODO | | nios2: | TODO | | openrisc: | TODO | | parisc: | TODO | | powerpc: | ok | | s390: | ok | | score: | ok | | sh: | ok | | sparc: | ok | | tile: | ok | | um: | ok | | unicore32: | ok | | x86: | ok | | xtensa: | ok | ----------------------- For generic kernel features that need architecture support, the arch-support.txt file in each feature directory shows the arch support matrix, for all upstream Linux architectures. The meaning of entries in the tables is: | ok | # feature supported by the architecture |TODO| # feature not yet supported by the architecture | .. | # feature cannot be supported by the hardware This directory structure can be used in the future to add other files - such as porting guides, testing description, etc. The Documentation/features/ hierarchy may also include generic kernel features that works on every architecture, in that case the arch-support.txt file will list every architecture as supported. To list an architecture's unsupported features, just do something like: triton:~/tip> git grep -lE 'x86.*TODO' Documentation/features/*/*/arch-support.txt Documentation/features/lib/strncasecmp/arch-support.txt Documentation/features/time/arch-tick-broadcast/arch-support.txt which will print the list of not yet supported features. The Documentation/features/list-arch.sh script will print the current support matrix of one architecture: triton:~/tip> Documentation/features/list-arch.sh # # Kernel feature support matrix of the 'x86' architecture: # core/ BPF-JIT : ok | HAVE_BPF_JIT # arch supports BPF JIT optimizations core/ generic-idle-thread : ok | GENERIC_SMP_IDLE_THREAD # arch makes use of the generic SMP idle thread facility core/ jump-labels : ok | HAVE_ARCH_JUMP_LABEL # arch supports live patched, high efficiency branches core/ tracehook : ok | HAVE_ARCH_TRACEHOOK # arch supports tracehook (ptrace) register handling APIs debug/ gcov-profile-all : ok | ARCH_HAS_GCOV_PROFILE_ALL # arch supports whole-kernel GCOV code coverage profiling debug/ KASAN : ok | HAVE_ARCH_KASAN # arch supports the KASAN runtime memory checker debug/ kgdb : ok | HAVE_ARCH_KGDB # arch supports the kGDB kernel debugger debug/ kprobes : ok | HAVE_KPROBES # arch supports live patched kernel probe debug/ kprobes-on-ftrace : ok | HAVE_KPROBES_ON_FTRACE # arch supports combined kprobes and ftrace live patching debug/ kretprobes : ok | HAVE_KRETPROBES # arch supports kernel function-return probes debug/ optprobes : ok | HAVE_OPTPROBES # arch supports live patched optprobes debug/ stackprotector : ok | HAVE_CC_STACKPROTECTOR # arch supports compiler driven stack overflow protection debug/ uprobes : ok | ARCH_SUPPORTS_UPROBES # arch supports live patched user probes debug/ user-ret-profiler : ok | HAVE_USER_RETURN_NOTIFIER # arch supports user-space return from system call profiler io/ dma-api-debug : ok | HAVE_DMA_API_DEBUG # arch supports DMA debug facilities io/ dma-contiguous : ok | HAVE_DMA_CONTIGUOUS # arch supports the DMA CMA (continuous memory allocator) io/ dma_map_attrs : ok | HAVE_DMA_ATTRS # arch provides dma_*map*_attrs() APIs io/ sg-chain : ok | ARCH_HAS_SG_CHAIN # arch supports chained scatter-gather lists lib/ strncasecmp : TODO | __HAVE_ARCH_STRNCASECMP # arch provides an optimized strncasecmp() function locking/ cmpxchg-local : ok | HAVE_CMPXCHG_LOCAL # arch supports the this_cpu_cmpxchg() API locking/ lockdep : ok | LOCKDEP_SUPPORT # arch supports the runtime locking correctness debug facility locking/ queued-rwlocks : ok | ARCH_USE_QUEUED_RWLOCKS # arch supports queued rwlocks locking/ queued-spinlocks : ok | ARCH_USE_QUEUED_SPINLOCKS # arch supports queued spinlocks locking/ rwsem-optimized : ok | Optimized asm/rwsem.h # arch provides optimized rwsem APIs perf/ kprobes-event : ok | HAVE_REGS_AND_STACK_ACCESS_API # arch supports kprobes with perf events perf/ perf-regs : ok | HAVE_PERF_REGS # arch supports perf events register access perf/ perf-stackdump : ok | HAVE_PERF_USER_STACK_DUMP # arch supports perf events stack dumps sched/ numa-balancing : ok | ARCH_SUPPORTS_NUMA_BALANCING # arch supports NUMA balancing seccomp/ seccomp-filter : ok | HAVE_ARCH_SECCOMP_FILTER # arch supports seccomp filters time/ arch-tick-broadcast : TODO | ARCH_HAS_TICK_BROADCAST # arch provides tick_broadcast() time/ clockevents : ok | GENERIC_CLOCKEVENTS # arch support generic clock events time/ context-tracking : ok | HAVE_CONTEXT_TRACKING # arch supports context tracking for NO_HZ_FULL time/ irq-time-acct : ok | HAVE_IRQ_TIME_ACCOUNTING # arch supports precise IRQ time accounting time/ modern-timekeeping : ok | !ARCH_USES_GETTIMEOFFSET # arch does not use arch_gettimeoffset() anymore time/ virt-cpuacct : ok | HAVE_VIRT_CPU_ACCOUNTING # arch supports precise virtual CPU time accounting vm/ ELF-ASLR : ok | ARCH_HAS_ELF_RANDOMIZE # arch randomizes the stack, heap and binary images of ELF binaries vm/ huge-vmap : ok | HAVE_ARCH_HUGE_VMAP # arch supports the ioremap_pud_enabled() and ioremap_pmd_enabled() VM APIs vm/ ioremap_prot : ok | HAVE_IOREMAP_PROT # arch has ioremap_prot() vm/ numa-memblock : ok | HAVE_MEMBLOCK_NODE_MAP # arch supports NUMA aware memblocks vm/ PG_uncached : ok | ARCH_USES_PG_UNCACHED # arch supports the PG_uncached page flag vm/ pmdp_splitting_flush : ok | __HAVE_ARCH_PMDP_SPLITTING_FLUSH # arch supports the pmdp_splitting_flush() VM API vm/ pte_special : ok | __HAVE_ARCH_PTE_SPECIAL # arch supports the pte_special()/pte_mkspecial() VM APIs vm/ THP : ok | HAVE_ARCH_TRANSPARENT_HUGEPAGE # arch supports transparent hugepages Cc: <linux-api@vger.kernel.org> Cc: <linux-arch@vger.kernel.org> Cc: <linux-kernel@vger.kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: H.
