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": "201a15428bd54f83eccec8b7c64a04b8f9431204", "tree": "326fcce64ce96657253fd141a3f4a767ac95418a", "parents": [ "e3d4d28b1c8cc7c26536a50b43d86ccd39878550" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:35 2009 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:35 2009 +0000" }, "message": "FS-Cache: Handle pages pending storage that get evicted under OOM conditions\n\nHandle netfs pages that the vmscan algorithm wants to evict from the pagecache\nunder OOM conditions, but that are waiting for write to the cache.

This means that some data won\u0027t make it into the\ncache this time. To support this, a new FS-Cache function is added\nfscache_maybe_release_page() that replaces what the netfs releasepage()\nfunctions used to do with respect to the cache.\n\nThe decisions fscache_maybe_release_page() makes are counted and displayed\nthrough /proc/fs/fscache/stats on a line labelled \"VmScan\". There are four\ncounters provided: \"nos\u003dN\" - pages that weren\u0027t pending storage; \"gon\u003dN\" -\npages that were pending storage when we first looked, but weren\u0027t by the time\nwe got the object lock; \"bsy\u003dN\" - pages that we ignored as they were actively\nbeing written when we looked; and \"can\u003dN\" - pages that we cancelled the storage\nof.\n\nWhat I\u0027d really like to do is alter the behaviour of the cancellation\nheuristics, depending on how necessary it is to expel pages. If there are\nplenty of other pages that aren\u0027t waiting to be written to the cache that\ncould be ejected first, then it would be nice to hold up on immediate\ncancellation of cache writes - but I don\u0027t see a way of doing that.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "9886e836a6a5dbd273dc55b17e713f0a188d137f", "tree": "87f8e3d719ae43d5d5d5911d70d6c7b3aa66be32", "parents": [ "1e23502cc57cef33455ac7cb9111e3c6d991a894" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Aug 27 13:09:06 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 27 12:22:08 2009 -0700" }, "message": "AFS: Stop readlink() on AFS crashing due to NULL \u0027file\u0027 ptr\n\nkAFS crashes when asked to read a symbolic link because page_getlink()\npasses a NULL file pointer to read_mapping_page(), but afs_readpage()\nexpects a file pointer from which to extract a key.\n\nModify afs_readpage() to request the appropriate key from the calling\nprocess\u0027s keyrings if a file struct is not supplied with one attached.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6566abdbd0566fc1b5950c9f87ef57c7443d6fa8", "tree": "142643f08a12be27547baabf40378fda20f648ff", "parents": [ "d29a2e943867bfa48f72ee6e99723a1b29fe6f7e" ], "author": { "name": "Matt Kraai", "email": "kraai@ftbfs.org", "time": "Fri Apr 17 12:56:38 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 17 09:55:19 2009 -0700" }, "message": "AFS: Guard afs_file_readpage_read_complete() definition with CONFIG_AFS_FSCACHE\n\nIf CONFIG_AFS_FSCACHE is not defined, the following warning is displayed when\nfs/afs/file.c is compiled:\n\n fs/afs/file.c:111: warning: ‘afs_file_readpage_read_complete’ defined but not used\n\nThis occurs because all calls to this function are guarded by\nCONFIG_AFS_FSCACHE.

(But even then, page_table_lock is still used to guard page\ntable allocation, and anon_vma allocation.)\n\nIn this implementation, the spinlock is tucked inside the struct page of the\npage table page: with a BUILD_BUG_ON in case it overflows - which it would in\nthe case of 32-bit PA-RISC with spinlock debugging enabled.\n\nSplitting the lock is not quite for free: another cacheline access. Ideally,\nI suppose we would use split ptlock only for multi-threaded processes on\nmulti-cpu machines; but deciding that dynamically would have its own costs.\nSo for now enable it by config, at some number of cpus - since the Kconfig\nlanguage doesn\u0027t support inequalities, let preprocessor compare that with\nNR_CPUS. But I don\u0027t think it\u0027s worth being user-configurable: for good\ntesting of both split and unsplit configs, split now at 4 cpus, and perhaps\nchange that to 8 later.\n\nThere is a benefit even for singly threaded processes: kswapd can be attacking\none part of the mm while another part is busy faulting.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "27496a8c67bef4d789d8e3c8317ca35813a507ae", "tree": "fe99a34fe5a800e41af61853e7444ddddf45d014", "parents": [ "7d877f3bda870ab5f001bd92528654471d5966b3" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Oct 21 03:20:48 2005 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Oct 28 08:16:47 2005 -0700" }, "message": "[PATCH] gfp_t: fs/*\n\n - -\u003ereleasepage() annotated (s/int/gfp_t), instances updated\n - missing gfp_t in fs/* added\n - fixed misannotation from the original sweep caught by bitwise checks:\n XFS used __nocast both for gfp_t and for flags used by XFS allocator.\n The latter left with unsigned int __nocast; we might want to add a\n different type for those but for now let\u0027s leave them alone.
