The spell is broken when the migrate thread catches\nthe resource with a lock.\n\nThe fix is to make the migrate thread also consider the reference map.\n\nThis usage pattern can be triggered by userspace on userdlm locks and flocks.\n\nSigned-off-by: Sunil Mushran \u003csunil.mushran@oracle.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "a48a982a6bd3896274dd643397c72da9258411e2", "tree": "d94208ff3ec315325eef3eaf365a9d71451ba3b2", "parents": [ "2811036a19624168ff9342bb85421dbbb1d2ac0d" ], "author": { "name": "David Sterba", "email": "dsterba@suse.cz", "time": "Tue Nov 02 23:36:02 2010 +0100" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Thu Nov 18 14:10:55 2010 -0800" }, "message": "fs/ocfs2/dlm: Use GFP_ATOMIC under spin_lock\n\ncoccinelle check scripts/coccinelle/locks/call_kern.cocci found that\nin fs/ocfs2/dlm/dlmdomain.c an allocation with GFP_KERNEL is done\nwith locks held:\n\ndlm_query_region_handler\n spin_lock(dlm_domain_lock)\n dlm_match_regions\n kmalloc(GFP_KERNEL)\n\nChange it to GFP_ATOMIC.\n\nSigned-off-by: David Sterba \u003cdsterba@suse.cz\u003e\nCC: Joel Becker \u003cjoel.becker@oracle.com\u003e\nCC: Mark Fasheh \u003cmfasheh@suse.com\u003e\nCC: ocfs2-devel@oss.oracle.com\n\n--\nExists in v2.6.37-rc1 and current linux-next.\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "fc3718918f13ad72827d62d36ea0f5fb55090644", "tree": "4f9551256e02d08be37bab137f3d94182a67504c", "parents": [ "7bdb0d18bfd381cc5491eb95973ec5604b356c7e", "d4396eafe402b710a8535137b3bf2abe6c059a15" ], "author": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Fri Oct 15 13:03:09 2010 -0700" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Fri Oct 15 13:03:09 2010 -0700" }, "message": "Merge branch \u0027globalheartbeat-2\u0027 of git://oss.oracle.com/git/smushran/linux-2.6 into ocfs2-merge-window\n\nConflicts:\n\tfs/ocfs2/ocfs2.h\n" }, { "commit": "4d94aa1b1d437f9513ddc89974d8bd214b8304f6", "tree": "81618849d288255603f71828d3f1151f74495094", "parents": [ "43695d095dfaf266a8a940d9b07eed7f46076b49" ], "author": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Sat Oct 09 10:27:04 2010 -0700" }, "committer": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Sat Oct 09 10:27:04 2010 -0700" }, "message": "ocfs2/cluster: Bump up dlm protocol to version 1.1\n\ndlm protocol 1.1. activates messages DLM_QUERY_REGION and DLM_QUERY_NODEINFO\nthat are a must for global heartbeat.\n\nIt also activates o2hb_global_heartbeat_active().\n\nSigned-off-by: Sunil Mushran \u003csunil.mushran@oracle.com\u003e\n" }, { "commit": "18cfdf1b1a8e83b09e4185c02396257ce7e7bee3", "tree": "b48ddd98926f0763be53bef5414adf82e1f5cb8d", "parents": [ "5f3c6d9c615770708df464c170316f83cf437242" ], "author": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Thu Oct 07 16:47:03 2010 -0700" }, "committer": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Thu Oct 07 16:47:03 2010 -0700" }, "message": "\nocfs2/dlm: Add message DLM_QUERY_NODEINFO\n\nAdds new dlm message DLM_QUERY_NODEINFO that sends the attributes of all\nregistered nodes.

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": "14741472a05245ed5778aa0aec055e1f920b6ef8", "tree": "0384fc0f8c3439a4bb2900bc725dae8a1f7924dd", "parents": [ "b54c2ca475fa7d7450a45b6d778dae9dbe0bcbfe" ], "author": { "name": "Srinivas Eeda", "email": "srinivas.eeda@oracle.com", "time": "Mon Mar 22 16:50:47 2010 -0700" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Mar 23 18:22:59 2010 -0700" }, "message": "ocfs2: Fix a race in o2dlm lockres mastery\n\nIn o2dlm, the master of a lock resource keeps a map of all interested\nnodes.

This is intentional to\nkeep the interface simple.\n\nBecause there is no asynchronous notification, there is no way for a\nprocess holding a lock to know another node needs the lock. This is the\nnumber one complaint of ocfs2_dlmfs users. Turns out, we can solve this\nvery easily. We add poll() support to ocfs2_dlmfs. When a BAST is\nreceived, the lock\u0027s file descriptor will receive POLLIN.\n\nThis is trivial to implement. Userdlm already has an appropriate\nwaitqueue, and the lock knows when it is blocked.\n\nWe add the \"bast\" capability to tell userspace this is available.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nAcked-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "14a437c2b67aeee2a989a5d9c7e19094355d2fed", "tree": "5fd3961361ed131bc7eb2ceded99ddba9a38449c", "parents": [ "399ff3a748cf4c8c853e96dd477153202636527b" ], "author": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Thu Feb 04 15:37:27 2010 -0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Fri Feb 26 15:41:13 2010 -0800" }, "message": "ocfs2_dlmfs: Add capabilities parameter.\n\nOver time, dlmfs has added some features that were not part of the\ninitial ABI.
