Independent processes\naccessing the same file synchronize over a single lock, even though\nthey have no need for synchronization at all.\n\nUnder high utilization this can cause llseek to scale very poorly on larger\nsystems.\n\nThis patch does some rethinking of the llseek locking model:\n\nFirst the 64bit f_pos is not necessarily atomic without locks\non 32bit systems. This can already cause races with read() today.\nThis was discussed on linux-kernel in the past and deemed acceptable.\nThe patch does not change that.\n\nLet\u0027s look at the different seek variants:\n\nSEEK_SET: Doesn\u0027t really need any locking.\nIf there\u0027s a race one writer wins, the other loses.\n\nFor 32bit the non atomic update races against read()\nstay the same. Without a lock they can also happen\nagainst write() now. The read() race was deemed\nacceptable in past discussions, and I think if it\u0027s\nok for read it\u0027s ok for write too.\n\n\u003d\u003e Don\u0027t need a lock.\n\nSEEK_END: This behaves like SEEK_SET plus it reads\nthe maximum size too. Reading the maximum size would have the\n32bit atomic problem. But luckily we already have a way to read\nthe maximum size without locking (i_size_read), so we\ncan just use that instead.\n\nWithout i_mutex there is no synchronization with write() anymore,\nhowever since the write() update is atomic on 64bit it just behaves\nlike another racy SEEK_SET. On non atomic 32bit it\u0027s the same\nas SEEK_SET.\n\n\u003d\u003e Don\u0027t need a lock, but need to use i_size_read()\n\nSEEK_CUR: This has a read-modify-write race window\non the same file. One could argue that any application\ndoing unsynchronized seeks on the same file is already broken.\nBut for the sake of not adding a regression here I\u0027m\nusing the file-\u003ef_lock to synchronize this.

is included by sched.h and module.h and thus ends up being\nincluded when building most .c files. percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed. Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "d812e575822a2b7ab1a7cadae2571505ec6ec2bd", "tree": "b94dad3a91d968a7851b65ce9f3f4960d9d99d6b", "parents": [ "fc7f99cf36ebae853639dabb43bc2f0098c59aef" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 19 13:55:17 2010 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 19 13:55:17 2010 -0400" }, "message": "NFS: Prevent another deadlock in nfs_release_page()\n\nWe should not attempt to free the page if __GFP_FS is not set.

This patch intends to actually give us real O_SYNC\nsemantics in addition to the O_DSYNC semantics. After Jan\u0027s O_SYNC\npatches which are required before this patch it\u0027s actually surprisingly\nsimple, we just need to figure out when to set the datasync flag to\nvfs_fsync_range and when not.\n\nThis patch renames the existing O_SYNC flag to O_DSYNC while keeping it\u0027s\nnumerical value to keep binary compatibility, and adds a new real O_SYNC\nflag. To guarantee backwards compatiblity it is defined as expanding to\nboth the O_DSYNC and the new additional binary flag (__O_SYNC) to make\nsure we are backwards-compatible when compiled against the new headers.\n\nThis also means that all places that don\u0027t care about the differences can\njust check O_DSYNC and get the right behaviour for O_SYNC, too - only\nplaces that actuall care need to check __O_SYNC in addition. Drivers and\nnetwork filesystems have been updated in a fail safe way to always do the\nfull sync magic if O_DSYNC is set. The few places setting O_SYNC for\nlower layers are kept that way for now to stay failsafe.\n\nWe enforce that O_DSYNC is set when __O_SYNC is set early in the open path\nto make sure we always get these sane options.\n\nNote that parisc really screwed up their headers as they already define a\nO_DSYNC that has always been a no-op. We try to repair it by using it for\nthe new O_DSYNC and redefinining O_SYNC to send both the traditional\nO_SYNC numerical value _and_ the O_DSYNC one.\n\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: \"David S.

The\npage is not marked as up to date because there are portions\nof the page which do not contain valid file contents.\n\nWhen a read call comes in for a portion of the page, the\ncontents of the page must be read in the from the server.\nHowever, since the page may already contain some modified\ndata, that modified data must be written to the server\nbefore the file contents can be read back in the from server.\nAnd, since the writing and reading can not be done atomically,\nthe data must be written and committed to stable storage on\nthe server for safety purposes. This means either a\nFILE_SYNC WRITE or a UNSTABLE WRITE followed by a COMMIT.\nThis has been discussed at length previously.\n\nThis algorithm could be described as modify-write-read. It\nis most efficient when the application only updates pages\nand does not read them.\n\nMy proposed solution is to add a heuristic to decide whether\nto do this modify-write-read algorithm or switch to a read-\nmodify-write algorithm when initially allocating the page\nin the write system call path. The heuristic uses the modes\nthat the file was opened with, the offset in the page to\nread from, and the size of the region to read.\n\nIf the file was opened for reading in addition to writing\nand the page would not be filled completely with data from\nthe user level, then read in the old contents of the page\nand mark it as Uptodate before copying in the new data. If\nthe page would be completely filled with data from the user\nlevel, then there would be no reason to read in the old\ncontents because they would just be copied over.\n\nThis would optimize for applications which randomly access\nand update portions of files. The linkage editor for the\nC compiler is an example of such a thing.\n\nI tested the attached patch by using rpmbuild to build the\ncurrent Fedora rawhide kernel. The kernel without the\npatch generated about 269,500 WRITE requests. The modified\nkernel containing the patch generated about 261,000 WRITE\nrequests. Thus, about 8,500 fewer WRITE requests were\ngenerated. I suspect that many of these additional\nWRITE requests were probably FILE_SYNC requests to WRITE\na single page, but I didn\u0027t test this theory.\n\nThe difference between this patch and the previous one was\nto remove the unneeded PageDirty() test. I then retested to\nensure that the resulting system continued to behave as\ndesired.\n\n\tThanx...\n\n\t\tps\n\nSigned-off-by: Peter Staubach \u003cstaubach@redhat.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "074cc1deec5dee63fcd5d966b36fa4f3765b50fc", "tree": "14508949385a168ab2e43ca5bf7423473f25d839", "parents": [ "c140aa91357c415c91269884518fa1d6fdebc20d" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Aug 10 08:54:13 2009 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Aug 10 08:54:13 2009 -0400" }, "message": "NFS: Add a -\u003emigratepage() aop for NFS\n\nMake NFS a bit more friendly to NUMA and memory hot removal...\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "405f55712dfe464b3240d7816cc4fe4174831be2", "tree": "96c425ea7fa8b31058b8f83a433c5e5265c8ebc7", "parents": [ "f9fabcb58a6d26d6efde842d1703ac7cfa9427b6" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Sat Jul 11 22:08:37 2009 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Jul 12 12:22:34 2009 -0700" }, "message": "headers: smp_lock.h redux\n\n* Remove smp_lock.h from files which don\u0027t need it (including some headers!)\n* Add smp_lock.h to files which do need it\n* Make smp_lock.h include conditional in hardirq.h\n It\u0027s needed only for one kernel_locked() usage which is under CONFIG_PREEMPT\n\n This will make hardirq.h inclusion cheaper for every PREEMPT\u003dn config\n (which includes allmodconfig/allyesconfig, BTW)\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bf40d3435caf49369058b1ed6bbc92f8e2bd92f1", "tree": "386cfc460a65febcbfbf46aeab3f1a817a9bd3ba", "parents": [ "5cd973c44a92f4abf8f7084c804089b3eaa7b4bf" ], "author": { "name": "Suresh Jayaraman", "email": "sjayaraman@suse.de", "time": "Wed Jun 17 18:02:09 2009 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jun 17 18:02:09 2009 -0700" }, "message": "NFS: add support for splice writes\n\nAdds support for splice writes.

This bug could\ncause filesystem deadlocks.\n\nThe funny thing with having a gfp_t mask there is that it doesn\u0027t really\nallow the caller to arbitrarily tinker with the context in which it can be\ncalled. It couldn\u0027t ever be GFP_ATOMIC, for example, because it needs to\ntake the page lock. The only thing any callers care about is __GFP_FS\nanyway, so turn that into a single flag.\n\nAdd a new flag for write_begin, AOP_FLAG_NOFS.

Change __grab_cache_page to\naccept a nofs argument as well, to honour that flag (while we\u0027re there,\nchange the name to grab_cache_page_write_begin which is more instructive\nand does away with random leading underscores).\n\nThis is really a more flexible way to go in the end anyway -- if a\nfilesystem happens to want any extra allocations aside from the pagecache\nones in ints write_begin function, it may now use GFP_KERNEL (rather than\nGFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a\nrandom example).\n\n[kosaki.motohiro@jp.fujitsu.com: fix ubifs]\n[kosaki.motohiro@jp.fujitsu.com: fix fuse]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.28.x]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Cleaned up the calling convention: just pass in the AOP flags\n untouched to the grab_cache_page_write_begin() function.
