Reference count summation\nmay then see the decrement without having seen the previous increment,\nleading to lower than expected count. A module which never has its\nactual reference drop below 1 may return a reference count of 0 due to\nthis race.\n\nModule removal generally runs under stop_machine, which prevents this\nrace causing bugs due to removal of in-use modules. However there are\nother real bugs in module.c code and driver code (module_refcount is\nexported) where the callers do not run under stop_machine.\n\nFix this by maintaining running per-cpu counters for the number of\nmodule refcount increments and the number of refcount decrements. The\nincrements are tallied after the decrements, so any decrement seen will\nalways have its corresponding increment counted. The final refcount is\nthe difference of the total increments and decrements, preventing a\nlow-refcount from being returned.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "449cedf099b23a250e7d61982e35555ccb871182", "tree": "75c205a2a44146196f916cbc4ec282751f7dad34", "parents": [ "b66696e3c0d8fc01efdbc701eba1276618332cb3" ], "author": { "name": "Eric Paris", "email": "eparis@redhat.com", "time": "Mon Apr 05 16:16:26 2010 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 05 13:19:45 2010 -0700" }, "message": "audit: preface audit printk with audit\n\nThere have been a number of reports of people seeing the message:\n\"name_count maxed, losing inode data: dev\u003d00:05, inode\u003d3185\"\nin dmesg.

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": "570b8fb505896e007fd3bb07573ba6640e51851d", "tree": "fd36f685aa2028628605733708bbf7d1af62f3ec", "parents": [ "9623e5a23724d09283c238960946ec6f65733afe" ], "author": { "name": "Mathieu Desnoyers", "email": "mathieu.desnoyers@efficios.com", "time": "Tue Mar 30 00:04:00 2010 +0100" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Tue Mar 30 17:15:38 2010 +1100" }, "message": "CRED: Fix memory leak in error handling\n\nFix a memory leak on an OOM condition in prepare_usermodehelper_creds().\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "292f60c0c4ab44aa2d589ba03c12e64a3b3c5e38", "tree": "0c33c9b23202a27c768dee45776503c9ec6b8306", "parents": [ "e36673ec5126f15a8cddf6049aede7bdcf484c26" ], "author": { "name": "Julia Lawall", "email": "julia@diku.dk", "time": "Mon Mar 29 17:37:02 2010 +0200" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Mon Mar 29 15:23:24 2010 -0400" }, "message": "ring-buffer: Add missing unlock\n\nIn some error handling cases the lock is not unlocked.

Currently we test the cgroup freezer\nstate of the resuming tasks to see if the cgroup is FROZEN. If so\nthen we don\u0027t thaw the task. However, the FREEZING state also indicates\nthat the task should remain frozen.\n\nThis also avoids a problem pointed out by Oren Ladaan: the freezer state\ntransition from FREEZING to FROZEN is updated lazily when userspace reads\nor writes the freezer.state file in the cgroup filesystem. This means that\nresume will thaw tasks in cgroups which should be in the FROZEN state if\nthere is no read/write of the freezer.state file to trigger this\ntransition before suspend.\n\nNOTE: Another \"simple\" solution would be to always update the cgroup\nfreezer state during resume. However it\u0027s a bad choice for several reasons:\nUpdating the cgroup freezer state is somewhat expensive because it requires\nwalking all the tasks in the cgroup and checking if they are each frozen.\nWorse, this could easily make resume run in N^2 time where N is the number\nof tasks in the cgroup. Finally, updating the freezer state from this code\npath requires trickier locking because of the way locks must be ordered.\n\nInstead of updating the freezer state we rely on the fact that lazy\nupdates only manage the transition from FREEZING to FROZEN. We know that\na cgroup with the FREEZING state may actually be FROZEN so test for that\nstate too. This makes sense in the resume path even for partially-frozen\ncgroups -- those that really are FREEZING but not FROZEN.\n\nReported-by: Oren Ladaan \u003corenl@cs.columbia.edu\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Rafael J.

This causes\nthe shift decrement to underflow, which causes the loop to never exit.\n\nThe simplest fix would be simply to do a:\n\tif (shift)\n\t\tshift--;\n\nHowever that is not optimal, as we know the cycle offset is larger\nthen the interval \u003c\u003c shift, the above would make shift drop to zero,\nthen we would be spinning for quite awhile accumulating at interval\nchunks at a time.\n\nInstead, this patch only decreases shift if the offset is smaller\nthen cycle_interval \u003c\u003c shift. This makes sure we accumulate using\nthe largest chunks possible without overflowing tick_length, and limits\nthe number of iterations through the loop.\n\nThis issue was found and reported by Sonic Zhang, who also tested the fix.\nMany thanks your explanation and testing!\n\nReported-by: Sonic Zhang \u003csonic.adi@gmail.com\u003e\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nTested-by: Sonic Zhang \u003csonic.adi@gmail.com\u003e\nLKML-Reference: \u003c1268948850-5225-1-git-send-email-johnstul@us.ibm.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "d2f1e15b661e71fd52111f51c99a6ce41384e9ef", "tree": "8731e7e772e6f825ebbc6eef7681bc46302149bd", "parents": [ "40b7e05e17eef31ff30fe08dfc2424ef653a792c", "220bf991b0366cc50a94feede3d7341fa5710ee4" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 22 18:46:57 2010 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 22 18:47:01 2010 +0100" }, "message": "Merge commit \u0027v2.6.34-rc2\u0027 into perf/core\n\nMerge reason: Pick up latest perf fixes from upstream.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "8c2eb4805d422bdbf60ba00ff233c794d23c3c00", "tree": "add5be0a86cb9453d7d8c6d08847013137a98806", "parents": [ "0cff810f54b3b52075c27f7a7021d5b195264b6c" ], "author": { "name": "Colin Ian King", "email": "colin.king@canonical.com", "time": "Fri Mar 19 10:28:02 2010 +0000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Mar 21 19:30:13 2010 +0100" }, "message": "softlockup: Stop spurious softlockup messages due to overflow\n\nEnsure additions on touch_ts do not overflow.

This saves space when there are lots\nof events being recorded at 4 byte boundaries.\n\nThe ring buffer has a zero copy method to write into the buffer, with\nthe reserving of space and then committing it. This may cause problems\nwhen writing an 8 byte word into a 4 byte alignment (not 8). For x86 and\nPPC this is not an issue, but on some architectures this would cause an\nout-of-alignment exception.\n\nThis patch uses CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to determine\nif it is OK to use 4 byte alignments on 64 bit machines. If it is not,\nit forces the ring buffer event header to be 8 bytes and not 4,\nand will align the length of the data to be 8 byte aligned.\nThis keeps the data payload at 8 byte alignments and will allow these\nmachines to run without issue.\n\nThe trick to this is that the header can be either 4 bytes or 8 bytes\ndepending on the length of the data payload. The 4 byte header\nhas a length field that supports up to 112 bytes. If the length of\nthe data is more than 112, the length field is set to zero, and the actual\nlength is stored in the next 4 bytes after the header.\n\nWhen CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is not set, the code forces\nzero in the 4 byte header forcing the length to be stored in the 4 byte\narray, even with a small data load. It also forces the length of the\ndata load to be 8 byte aligned. The combination of these two guarantee\nthat the data is always at 8 byte alignment.\n\nTested-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\n (on sparc64)\nReported-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: David S.
