* vmscan,memcg: reintroduce sc->may_swapKOSAKI Motohiro2009-04-211-4/+8
| | | | | | | | | | | | | | | | | | | | Commit a6dc60f8975ad96d162915e07703a4439c80dcf0 ("vmscan: rename sc.may_swap to may_unmap") removed the may_swap flag, but memcg had used it as a flag for "we need to use swap?", as the name indicate. And in the current implementation, memcg cannot reclaim mapped file caches when mem+swap hits the limit. re-introduce may_swap flag and handle it at get_scan_ratio(). This patch doesn't influence any scan_control users other than memcg.

* PM/Hibernate: Fix memory shrinkingRafael J. Wysocki2009-04-181-2/+3
| | | | | | | | | | | | | | | Commit d979677c4c0 ("mm: shrink_all_memory(): use sc.nr_reclaimed") broke the memory shrinking used by hibernation, becuse it did not update shrink_all_zones() in accordance with the other changes it made. Fix this by making shrink_all_zones() update sc->nr_reclaimed instead of overwriting its value.

* mm: pass correct mm when growing stackHugh Dickins2009-04-161-1/+1
| | | | | | | | | | | | | | | | | Tetsuo Handa reports seeing the WARN_ON(current->mm == NULL) in security_vm_enough_memory(), when do_execve() is touching the target mm's stack, to set up its args and environment. Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns an mm-less kernel thread to do the exec. And in any case, that vm_enough_memory check when growing stack ought to be done on the target mm, not on the execer's mm (though apart from the warning, it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

* shmem: respect MAX_LFS_FILESIZEHugh Dickins2009-04-131-5/+20
| | | | | | | | | | | | | | | | | | | | | SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account. Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to grow slightly bigger than that supposed maximum. Fix this by using the min of both (at build time not run time). And it happens that this calculation is good as far as 8MB pages on 32-bit or 16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that, it's truncated to such large numbers that we don't need to care.

* shmem: fix division by zeroYuri Tikhonov2009-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | | Fix a division by zero which we have in shmem_truncate_range() and shmem_unuse_inode() when using big PAGE_SIZE values (e.g. 256kB on ppc44x). With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large (0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type from 'unsigned long' to 'unsigned long long'. Hugh: reverted its unsigned long longs in shmem_truncate_range() and shmem_getpage(): the pagecache index cannot be more than an unsigned long, so the divisions by zero occurred in unreached code. It's a pity we need any ULL arithmetic here, but I found no pretty way to avoid it.

* mm: add /proc controls for pdflush threadsPeter W Morreale2009-04-071-12/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add /proc entries to give the admin the ability to control the minimum and maximum number of pdflush threads. This allows finer control of pdflush on both large and small machines. The rationale is simply one size does not fit all. Admins on large and/or small systems may want to tune the min/max pdflush thread count to best suit their needs. Right now the min/max is hardcoded to 2/8. While probably a fair estimate for smaller machines, large machines with large numbers of CPUs and large numbers of filesystems/block devices may benefit from larger numbers of threads working on different block devices. Even if the background flushing algorithm is radically changed, it is still likely that multiple threads will be involved and admins would still desire finer control on the min/max other than to have to recompile the kernel. The patch adds '/proc/sys/vm/nr_pdflush_threads_min' and '/proc/sys/vm/nr_pdflush_threads_max' with r/w permissions. The minimum value for nr_pdflush_threads_min is 1 and the maximum value is the current value of nr_pdflush_threads_max. This minimum is required since additional thread creation is performed in a pdflush thread itself. The minimum value for nr_pdflush_threads_max is the current value of nr_pdflush_threads_min and the maximum value can be 1000. Documentation/sysctl/vm.txt is also updated.

* mm: fix pdflush thread creation upper boundPeter W Morreale2009-04-071-6/+24
| | | | | | | | | | | | | | | | | | | | | | Fix a race on creating pdflush threads. Without the patch, it is possible to create more than MAX_PDFLUSH_THREADS threads, and this has been observed in practice on IO loaded SMP machines. The fix involves moving the lock around to protect the check against the thread count and correctly dealing with thread creation failure. This fix also _mostly_ repairs a race condition on how quickly the threads are created. The original intent was to create a pdflush thread (up to the max allowed) every second. Without this patch is is possible to create NCPUS pdflush threads concurrently. The 'mostly' caveat is because an assumption is made that thread creation will be successful. If we fail to create the thread, the miss is not considered fatal.
