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": "1d53661d26aa779dcd74f8a1c5a94e181cc101d8", "tree": "bc8dc31b5de84a641ae0c075644f7986990b053c", "parents": [ "091e635e6735fa4496c4a18e7e967b58e961303c" ], "author": { "name": "Mike Frysinger", "email": "vapier@gentoo.org", "time": "Tue Mar 23 13:35:17 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 24 16:31:20 2010 -0700" }, "message": "blackfin: enable DEBUG_SECTION_MISMATCH\n\nWe see only one section mismatch now after thousands of randconfigs, and a\nbug has been filed about that one.\n\nSigned-off-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b4b7a4ef097f288f724420b473dbf92a89c0ab7e", "tree": "23ad8101e3e77c32a8d1e1b95a9c1cd7f7a475b7", "parents": [ "e9ce335df51ff782035a15c261a3c0c9892a1767", "a3d3203e4bb40f253b1541e310dc0f9305be7c84" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Fri Mar 19 08:05:10 2010 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Fri Mar 19 08:05:10 2010 +0100" }, "message": "Merge branch \u0027master\u0027 into for-linus\n\nConflicts:\n\tblock/Kconfig\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "2cda2728aa1c8c006418a24f867b25e5eb7a32e2", "tree": "c23ec7c38d74237646c5453d96bfbbea4cadfee7", "parents": [ "f11c9c5c259cb2c3d698548dc3936f773ab1f5b9" ], "author": { "name": "Martin K.

The generic\nalgorithm instead merges pairs of equal length lists as early as possible,\nin recursive order. For either algorithm, the elements that extend the\nlist beyond power-of-two length are a special case, handled as nearly as\npossible as a \"rounding-up\" to a full POT.\n\nSome intuition for the locality of reference implications of merge order\nmay be gotten by watching this animation:\n\n http://www.sorting-algorithms.com/merge-sort\n\nSimon\u0027s algorithm requires only O(1) extra space rather than the generic\nalgorithm\u0027s O(log N), but in my non-recursive implementation the actual\nO(log N) data is merely a vector of ~20 pointers, which I\u0027ve put on the\nstack.\n\nLong-running list_sort() calls: If the list passed in may be long, or the\nclient\u0027s cmp() callback function is slow, the client\u0027s cmp() may\nperiodically invoke cond_resched() to voluntarily yield the CPU. All\ninner loops of list_sort() call back to cmp().\n\nStability of the sort: distinct elements that compare equal emerge from\nthe sort in the same order as with Mark\u0027s code, for simple test cases. A\nboot-time test is provided to verify this and other correctness\nrequirements.\n\nA kernel that uses drm.ko appears to run normally with this change; I have\nno suitable hardware to similarly test the use by UBIFS.\n\n[akpm@linux-foundation.org: style tweaks, fix comment, make list_sort_test __init]\nSigned-off-by: Don Mullis \u003cdon.mullis@gmail.com\u003e\nCc: Dave Airlie \u003cairlied@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Artem Bityutskiy \u003cdedekind@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d6a2eedfddcded92c8f9b0ac022a99c4134696b0", "tree": "6a0f38fbc74e839fc7712f8ebcb65cce75cdcc06", "parents": [ "a11d2b64e1f2556953120d516241243ea365f0ae" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:12 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify strnstr()\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a11d2b64e1f2556953120d516241243ea365f0ae", "tree": "efb406b16a33fedf9c239fd6c09d8fe74b0042b7", "parents": [ "8a6e25357d51d6ecf4ee21e9048f0416a085a79c" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:11 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify stricmp()\n\nRemoves 32 bytes on core2 with gcc 4.4.1:\n text data bss dec hex filename\n 3196 0 0 3196 c7c lib/string-BEFORE.o\n 3164 0 0 3164 c5c lib/string-AFTER.o\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0347af4ee3922220f6bfe74b87b526aa709a0365", "tree": "6b1f860991e3dae3fc110e02a1a838eb291b94ee", "parents": [ "33fd797b3e2c6a7663b9331150da0acdb31990a2" ], "author": { "name": "Simon Kagstrom", "email": "simon.kagstrom@netinsight.net", "time": "Fri Mar 05 13:42:49 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:32 2010 -0800" }, "message": "lkdtm: add debugfs access and loosen KPROBE ties\n\nAdd adds a debugfs interface and additional failure modes to LKDTM to\nprovide similar functionality to the provoke-crash driver submitted here:\n\n http://lwn.net/Articles/371208/\n\nCrashes can now be induced either through module parameters (as before)\nor through the debugfs interface as in provoke-crash.\n\nThe patch also provides a new \"direct\" interface, where KPROBES are not\nused, i.e., the crash is invoked directly upon write to the debugfs\nfile.

It is therefore time to\nenlist the aid of lockdep.\n\nThis set of patches is inspired by earlier work by Peter\nZijlstra and Thomas Gleixner, and takes the following approach:\n\no\tSet up separate lockdep classes for RCU, RCU-bh, and RCU-sched.\n\no\tSet up separate lockdep classes for each instance of SRCU.\n\no\tCreate primitives that check for being in an RCU read-side\n\tcritical section. These return exact answers if lockdep is\n\tfully enabled, but if unsure, report being in an RCU read-side\n\tcritical section. (We want to avoid false positives!)\n\tThe primitives are:\n\n\tFor RCU: rcu_read_lock_held(void)\n\n\tFor RCU-bh: rcu_read_lock_bh_held(void)\n\n\tFor RCU-sched: rcu_read_lock_sched_held(void)\n\n\tFor SRCU: srcu_read_lock_held(struct srcu_struct *sp)\n\no\tAdd rcu_dereference_check(), which takes a second argument\n\tin which one places a boolean expression based on the above\n\tprimitives and/or lockdep_is_held().\n\no\tA new kernel configuration parameter, CONFIG_PROVE_RCU, enables\n\trcu_dereference_check().

However, going up 1 level wouldn\u0027t give any more empty slot so\nit takes C and when the whole thing restarts nobody notices the high bit\nset beyond the top level.\n\nThis patch fixes the bug by changing the fail exit condition check to full\nid limit check.\n\nBased-on-patch-from: Eric Paris \u003ceparis@redhat.com\u003e\nReported-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9d3f1881abeae0494a27716b08fcf2d3264bb0fa", "tree": "f457dd2d35af29bc831b93865efa47229d0b9bee", "parents": [ "b6c58b1d987a5795086c5c2babd8c7367d2fdb8c", "bc10e875d4aeaa93a0d418d8b4346b72f5067ea0" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Feb 02 11:33:45 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Feb 02 11:33:45 2010 +0900" }, "message": "Merge branch \u0027sh/stable-updates\u0027\n" }, { "commit": "660e2acad81c19b404f7d7d06e57a6d5e6ce7426", "tree": "377b2e0f9d4219b301c1f3c16311a7710e2d4abc", "parents": [ "08b36c4a02b5a9db609fc6d93b9c41d7fa75713c" ], "author": { "name": "Chris Smith", "email": "chris.smith@st.com", "time": "Wed Jan 27 22:03:11 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jan 27 22:03:11 2010 +0900" }, "message": "sh: kmemleak support.\n\nEnables support for kmemleak on sh.\n\nSigned-off-by: Chris Smith \u003cchris.smith@st.com\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "51c24aaacaea90c8e87f1dec75a2ac7622b593f8", "tree": "9f54936c87764bef75e97395cb56b7d1e0df24c6", "parents": [ "4276e47e2d1c85a2477caf0d22b91c4f2377fba8", "6be325719b3e54624397e413efd4b33a997e55a3" ], "author": { "name": "David S.

The only reason I\n: can think of ever using gzip would be if you needed the additional\n: compression (eg, because you have limited flash to store the image.)\n:\n: I would argue that the default for ARM should therefore be LZO.\n\nThis patch:\n\nThe lzo compressor is worse than gzip at compression, but faster at\nextraction. Here are some figures for an ARM board I\u0027m working on:\n\nUncompressed size: 3.24Mo\ngzip 1.61Mo 0.72s\nlzo 1.75Mo 0.48s\n\nSo for a compression ratio that is still relatively close to gzip, it\u0027s\nmuch faster to extract, at least in that case.\n\nThis part contains:\n - Makefile routine to support lzo compression\n - Fixes to the existing lzo compressor so that it can be used in\n compressed kernels\n - wrapper around the existing lzo1x_decompress, as it only extracts one\n block at a time, while we need to extract a whole file here\n - config dialog for kernel compression\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: cleanup]\nSigned-off-by: Albin Tonnerre \u003calbin.tonnerre@free-electrons.com\u003e\nTested-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nAcked-by: \"H.
