In the case that a file was created, and utimes(...,NULL)\nwas used on it in the same second, the timestamp on the file moved backwards.\n\nAfter some digging, I found that this was being caused by tmpfs not having a\ntime granularity set, thus inheriting the default 1 second granularity.\n\nHugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11.\nUnfortunately, the granularity of CURRENT_TIME, often used in filesystems,\ndoes not match the default granularity set by alloc_super.

Therefore, migrate_pages() falls back to\ndefault processing.

OVERCOMMIT_GUESS algorithm in\n__vm_enough_memory().\n\n- why the kernel needed patching\n\n When the kernel can\u0027t allocate anonymous pages in practice, currnet\n OVERCOMMIT_GUESS could return success. This implementation might be\n the cause of oom kill in memory pressure situation.\n\n If the Linux runs with page reservation features like\n /proc/sys/vm/lowmem_reserve_ratio and without swap region, I think\n the oom kill occurs easily.\n\n- the overall design approach in the patch\n\n When the OVERCOMMET_GUESS algorithm calculates number of free pages,\n the reserved free pages are regarded as non-free pages.\n\n This change helps to avoid the pitfall that the number of free pages\n become less than the number which the kernel tries to keep free.\n\n- testing results\n\n I tested the patches using my test kernel module.\n\n If the patches aren\u0027t applied to the kernel, __vm_enough_memory()\n returns success in the situation but autual page allocation is\n failed.\n\n On the other hand, if the patches are applied to the kernel, memory\n allocation failure is avoided since __vm_enough_memory() returns\n failure in the situation.\n\n I checked that on i386 SMP 16GB memory machine. I haven\u0027t tested on\n nommu environment currently.\n\nThis patch adds totalreserve_pages for __vm_enough_memory().\n\nCalculate_totalreserve_pages() checks maximum lowmem_reserve pages and\npages_high in each zone.

Things which would require two or three syscalls with\n fadvise() can be done in a single syscall.\n\n- Using fadvise() in this manner is something not covered by POSIX.\n\nThe patch wires up the syscall for x86.\n\nThe sycall is implemented in the new fs/sync.c. The intention is that we can\nmove sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.\n\nDocumentation for the syscall is in fs/sync.c.\n\nA test app (sync_file_range.c) is in\nhttp://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.\n\nThe available-to-GPL-modules do_sync_file_range() is for knfsd: \"A COMMIT can\nsay NFS_DATA_SYNC or NFS_FILE_SYNC. I can skip the -\u003efsync call for\nNFS_DATA_SYNC which is hopefully the more common.\"\n\nNote: the `async\u0027 writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if\nthe queue is congested. This is trivial to fix: add a new flag bit, set\nwbc-\u003enonblocking.

Any pages which are currently under\nwriteout are skipped, whether or not they are dirty.\n\nLINUX_FADV_WRITE_WAIT: wait upon writeout of any dirty pages between file\noffsets `offset\u0027 and `offset+len\u0027.\n\nBy combining these two operations the application may do several things:\n\nLINUX_FADV_ASYNC_WRITE: push some or all of the dirty pages at the disk.\n\nLINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE: push all of the currently dirty\npages at the disk.\n\nLINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE, LINUX_FADV_WRITE_WAIT: push all\nof the currently dirty pages at the disk, wait until they have been written.\n\nIt should be noted that none of these operations write out the file\u0027s\nmetadata. So unless the application is strictly performing overwrites of\nalready-instantiated disk blocks, there are no guarantees here that the data\nwill be available after a crash.\n\nTo complete this suite of operations I guess we should have a \"sync file\nmetadata only\" operation. This gives applications access to all the building\nblocks needed for all sorts of sync operations. But sync-metadata doesn\u0027t fit\nwell with the fadvise() interface. Probably it should be a new syscall:\nsys_fmetadatasync().\n\nThe patch also diddles with the meaning of `endbyte\u0027 in sys_fadvise64_64().\nIt is made to represent that last affected byte in the file (ie: it is\ninclusive). Generally, all these byterange and pagerange functions are\ninclusive so we can easily represent EOF with -1.\n\nAs Ulrich notes, these two functions are somewhat abusive of the fadvise()\nconcept, which appears to be \"set the future policy for this fd\".\n\nBut these commands are a perfect fit with the fadvise() impementation, and\nseveral of the existing fadvise() commands are synchronous and don\u0027t affect\nfuture policy either. I think we can live with the slight incongruity.\n\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "469eb4d03878b676418f853011ebfb54ccf83a5e", "tree": "38b10385c6241778ca88c6015ded3ba68d39a23c", "parents": [ "604bf5a216e7f2d97cdf62614ca1281921531040" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Fri Mar 24 03:17:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 24 07:33:25 2006 -0800" }, "message": "[PATCH] filemap_fdatawrite_range() api: clarify -end parameter\n\nI had trouble understanding working out whether filemap_fdatawrite_range()\u0027s\n`end\u0027 parameter describes the last-byte-to-be-written or the last-plus-one.\nClarify that in comments.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b2455396be35383c4eebc6745cc718b1dd9e23df", "tree": "9ed4d43f1ca944c23372fad6554508f1747f5e2d", "parents": [ "151a44202d097ae8b1bbaa6d8d2f97df30e3cd1e" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Fri Mar 24 03:16:12 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 24 07:33:24 2006 -0800" }, "message": "[PATCH] cpuset: memory_spread_slab drop useless PF_SPREAD_PAGE check\n\nThe hook in the slab cache allocation path to handle cpuset memory\nspreading for tasks in cpusets with \u0027memory_spread_slab\u0027 enabled has a\nmodest performance bug.
