* [PATCH] ext3: Properly report backup block present in a groupGlauber de Oliveira Costa2006-03-241-7/+33
| | | | | | | | | | | | | | | In filesystems with the meta block group flag on, ext3_bg_num_gdb() fails to report the correct number of blocks used to store the group descriptor backups in a given group. It happens because meta_bg follows a different logic from the original ext3 backup placement in groups multiples of 3, 5 and 7.

* [PATCH] RLIMIT_CPU: fix handling of a zero limitAndrew Morton2006-03-241-1/+12
| | | | | | | | | | | | | | | | | | | | At present the kernel doesn't honour an attempt to set RLIMIT_CPU to zero seconds. But the spec says it should, and that's what 2.4.x does. Fixing this for real would involve some complexity (such as adding a new it-has-been-set flag to the task_struct, and testing that everwhere, instead of overloading the value of it_prof_expires). Given that a 2.4 kernel won't actually send the signal until one second has expired anyway, let's just handle this case by treating the caller's zero-seconds as one second.

* [PATCH] sys_setrlimit() cleanupAndrew Morton2006-03-241-11/+15
| | | | | | | | | | | | | | | | | | | - Whitespace cleanups - Make that expression comprehensible. There's a potential logic change here: we do the "is it_prof_expires equal to zero" test after converting it to seconds, rather than doing the comparison between raw cputime_t's. But given that it's in units of seconds anyway, that shouldn't change anything.

| | | | | | | | | | | | | | | | | It appears that console_setup() code only gets compiled into the kernel if CONFIG_PRINTK is enabled. One detrimental side-effect of this is that serial8250_console_setup() never gets invoked when CONFIG_PRINTK is not set, resulting in baud rate not being read/parsed from command line (i.e. console=ttyS0,115200n8 is ignored, at least the baud rate part...)

* [PATCH] msync(): perform dirty page levellingAndrew Morton2006-03-241-32/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems sensible to perform dirty page throttling in msync: as the application dirties pages we can kick off pdflush early, or even force the msync() caller to perform writeout, or even throttle the msync() caller. The main effect of this is to start disk writeback earlier if we've just discovered that a large amount of pagecache has been dirtied. (Otherwise it wouldn't happen for up to five seconds, next time pdflush wakes up). It also will cause the page-dirtying process to get panalised for dirtying those pages rather than whacking someone else with the problem. We should do this for munmap() and possibly even exit(), too. We drop the mmap_sem while performing the dirty page balancing. It doesn't seem right to hold mmap_sem for that long. Note that this patch only affects MS_ASYNC. MS_SYNC will be syncing all the dirty pages anyway. We note that msync(MS_SYNC) does a full-file-sync inside mmap_sem, and always has. We can fix that up... The patch also tightens up the mmap_sem coverage in sys_msync(): no point in taking it while we perform the incoming arg checking.

Does it have the potential to break existing apps? Hugh says "sys_shmdt() just does the wrong (unexpected) thing with a misaligned address: it'll fail on what you might expect it to succeed on, and only succeed on what it should definitely fail on. "That is, I think it behaves as if shmaddr gets rounded up, when the only understandable behaviour would be if it rounded it down. "Which does mean you'd have to be devious to see anything but EINVAL from a misaligned shmaddr there, so it's not terribly important."

* [PATCH] fadvise(): write commandsAndrew Morton2006-03-244-10/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new linux-specific fadvise extensions(): LINUX_FADV_ASYNC_WRITE: start async writeout of any dirty pages between file offsets `offset' and `offset+len'. Any pages which are currently under writeout are skipped, whether or not they are dirty. LINUX_FADV_WRITE_WAIT: wait upon writeout of any dirty pages between file offsets `offset' and `offset+len'. By combining these two operations the application may do several things: LINUX_FADV_ASYNC_WRITE: push some or all of the dirty pages at the disk. LINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE: push all of the currently dirty pages at the disk. LINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE, LINUX_FADV_WRITE_WAIT: push all of the currently dirty pages at the disk, wait until they have been written. It should be noted that none of these operations write out the file's metadata. So unless the application is strictly performing overwrites of already-instantiated disk blocks, there are no guarantees here that the data will be available after a crash. To complete this suite of operations I guess we should have a "sync file metadata only" operation. This gives applications access to all the building blocks needed for all sorts of sync operations. But sync-metadata doesn't fit well with the fadvise() interface. Probably it should be a new syscall: sys_fmetadatasync(). The patch also diddles with the meaning of `endbyte' in sys_fadvise64_64(). It is made to represent that last affected byte in the file (ie: it is inclusive). Generally, all these byterange and pagerange functions are inclusive so we can easily represent EOF with -1. As Ulrich notes, these two functions are somewhat abusive of the fadvise() concept, which appears to be "set the future policy for this fd". But these commands are a perfect fit with the fadvise() impementation, and several of the existing fadvise() commands are synchronous and don't affect future policy either. I think we can live with the slight incongruity. Cc: Michael Kerrisk <mtk-manpages@gmx.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] cpuset: remove useless local variable initializationPaul Jackson2006-03-241-1/+1
| | | | | | | | | | | | | Remove a useless variable initialization in cpuset __cpuset_zone_allowed(). The local variable 'allowed' is unconditionally set before use, later on in the code, so does not need to be initialized. Not that it seems to matter to the code generated any, as the compiler optimizes out the superfluous assignment anyway.

* [PATCH] cpuset: memory_spread_slab drop useless PF_SPREAD_PAGE checkPaul Jackson2006-03-241-3/+2
| | | | | | | | | | | | | | | | | | | The hook in the slab cache allocation path to handle cpuset memory spreading for tasks in cpusets with 'memory_spread_slab' enabled has a modest performance bug. The hook calls into the memory spreading handler alternate_node_alloc() if either of 'memory_spread_slab' or 'memory_spread_page' is enabled, even though the handler does nothing (albeit harmlessly) for the page case Fix - drop PF_SPREAD_PAGE from the set of flag bits that are used to trigger a call to alternate_node_alloc(). The page case is handled by separate hooks -- see the calls conditioned on cpuset_do_page_mem_spread() in mm/filemap.c Signed-off-by: Paul Jackson <pj@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] cpuset memory spread slab cache hooksPaul Jackson2006-03-244-6/+15
| | | | | | | | | | | | | | | | | | Change the kmem_cache_create calls for certain slab caches to support cpuset memory spreading. See the previous patches, cpuset_mem_spread, for an explanation of cpuset memory spreading, and cpuset_mem_spread_slab_cache for the slab cache support for memory spreading. The slab caches marked for now are: dentry_cache, inode_cache, some xfs slab caches, and buffer_head. This list may change over time. In particular, other file system types that are used extensively on large NUMA systems may want to allow for spreading their directory and inode slab cache entries.
