It turns out that the current\ngfs2 code saves off a process pointer when glocks is taken\nin both the glock and glock holder structures. Those\nstructures will persist in memory long after the process has\nended; pointers to poisoned memory.\n\nThis problem isn\u0027t caused by the 228540 fix; the new capability\nintroduced by the fix just uncovered the problem.\n\nI wrote this patch that avoids saving process pointers\nand instead saves off the process pid. Rather than\nreferencing the bad pointers, it now does process lookups.\nThere is special code that makes the output nicer for\nprinting holder information for processes that have ended.\n\nThis patch also adds a stub for the new \"sprint_symbol\"\nfunction that exists in Andrew Morton\u0027s -mm patch set, but\nwon\u0027t go into the base kernel until 2.6.22, since it adds\nfunctionality but doesn\u0027t fix a bug.\n\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "420d2a1028b906f24e836e37089a6ad55ab1848f", "tree": "a0fa71778dcec08d461aba2e75b045878b483498", "parents": [ "3b8249f6178cb2b68b9d683587797270125cc06a" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Sun Mar 18 16:05:27 2007 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue May 01 09:10:42 2007 +0100" }, "message": "[GFS2] Fix a bug on i386 due to evaluation order\n\nSince gcc didn\u0027t evaluate the last two terms of the expression in\nglock.c:1881 as a constant expression, it resulted in an error on\ni386 due to the lack of a 64bit divide instruction.

The callback on the iopen lock is\nonly ever called when i_nlink \u003d\u003d 0 and when a node is unable to deallocate\nit due to it still being in use on another node.

This simplifies the code for dealing with gfs2_holders\nas it removes one special case.\n\nThere are two new fields in struct gfs2_glock. gl_demote_state is the\nstate which the remote node has requested and gl_demote_time is the\ntime when the request came in.

The\ncode was too complicated and also hurts performance badly in the\ncase that the getdents64/readdir call isn\u0027t being followed by\nstat() and it wasn\u0027t even getting it right all the time when it\nwas.\n\nAs a result, on my test box an \"ls\" of a directory containing 250000\nfiles fell from about 7mins (freshly mounted, so nothing cached) to\nbetween about 15 to 25 seconds. When the directory content was cached,\nthe time taken fell from about 3mins to about 4 or 5 seconds.\n\nInterestingly in the cached case, running \"ls -l\" once reduced the time\ntaken for subsequent runs of \"ls\" to about 6 secs even without this\npatch. Now it turns out that there was a special case of glocks being\nused for prefetching the metadata, but because of the timeouts for these\nlocks (set to 10 secs) the metadata was being timed out before it was\nbeing used and this the prefetch code was constantly trying to prefetch\nthe same data over and over.\n\nCalling \"ls -l\" meant that the inodes were brought into memory and once\nthe inodes are cached, the glocks are not disposed of until the inodes\nare pushed out of the cache, thus extending the lifetime of the glocks,\nand thus bringing down the time for subsequent runs of \"ls\"\nconsiderably.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "1c1afa3c053d4ccdf44e5a4e159005cdfd48bfc6", "tree": "3e686ad4cf1ae2300e7190ff83afc3f3dd4ba740", "parents": [ "0a01707b289853f56d1c000057b27e243c039722", "ac33d0710595579e3cfca42dde2257eb0b123f6d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 09:13:20 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 09:13:20 2006 -0800" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/steve/gfs2-2.6-nmw\n\n* master.kernel.org:/pub/scm/linux/kernel/git/steve/gfs2-2.6-nmw: (73 commits)\n [DLM] Clean up lowcomms\n [GFS2] Change gfs2_fsync() to use write_inode_now()\n [GFS2] Fix indent in recovery.c\n [GFS2] Don\u0027t flush everything on fdatasync\n [GFS2] Add a comment about reading the super block\n [GFS2] Mount problem with the GFS2 code\n [GFS2] Remove gfs2_check_acl()\n [DLM] fix format warnings in rcom.c and recoverd.c\n [GFS2] lock function parameter\n [DLM] don\u0027t accept replies to old recovery messages\n [DLM] fix size of STATUS_REPLY message\n [GFS2] fs/gfs2/log.c:log_bmap() fix printk format warning\n [DLM] fix add_requestqueue checking nodes list\n [GFS2] Fix recursive locking in gfs2_getattr\n [GFS2] Fix recursive locking in gfs2_permission\n [GFS2] Reduce number of arguments to meta_io.c:getbuf()\n [GFS2] Move gfs2_meta_syncfs() into log.c\n [GFS2] Fix journal flush problem\n [GFS2] mark_inode_dirty after write to stuffed file\n [GFS2] Fix glock ordering on inode creation\n ...\n" }, { "commit": "0ac230699a0f3f0d15ad4e4ad99446dac5b4a21f", "tree": "c0d608cd584c3884492ec196544c6fcbf82a8fb8", "parents": [ "98f176fb32f33795b6d0f83856008b932123ab38" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Tue Nov 28 22:29:19 2006 -0800" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu Nov 30 10:37:18 2006 -0500" }, "message": "[GFS2] lock function parameter\n\nFix function parameter typing:\nfs/gfs2/glock.c:100: warning: function declaration isn\u0027t a prototype\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "b004157ab5b374a498a5874cda68c389219d23e7", "tree": "1e7d7d5c62f3e12cc453e763bbff139b47458be4", "parents": [ "ae619320b22f8e0b2bbe4a3a5ac2f9ccf08d7ec2" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu Nov 23 10:51:34 2006 -0500" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu Nov 30 10:36:42 2006 -0500" }, "message": "[GFS2] Fix journal flush problem\n\nThis fixes a bug which resulted in poor performance due to flushing\nthe journal too often.

Note that with GFS2, those two events might take place\non different nodes.\n\nAlso there are a number of other changes:\n\n o We use the Linux inode subsystem as it was intended to be\nused, wrt allocating GFS2 inodes\n o The Linux inode cache is now the point which we use for\nlocal enforcement of only holding one copy of the inode in\ncore at once (previous to this we used the glock layer).\n o We no longer use the unlinked \"special\" file. We just ignore it\ncompletely. This makes unlinking more efficient.\n o We now use the 4th block allocation state. The previously unused\nstate is used to track unlinked but still open inodes.\n o gfs2_inoded is no longer needed\n o Several fields are now no longer needed (and removed) from the in\ncore struct gfs2_inode\n o Several fields are no longer needed (and removed) from the in core\nsuperblock\n\nThere are a number of future possible optimisations and clean ups\nwhich have been made possible by this patch.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "382066da251132f768380f4852ed5afb72d88f80", "tree": "f8ae69e6b441452f9958f45cea15a0cf90baa39d", "parents": [ "9229f013495dcdae76e9942ebc2cfc69851fe10a" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed May 24 10:22:09 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed May 24 10:22:09 2006 -0400" }, "message": "[GFS2] Casts for printing 64bit numbers\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "320dd101e2d595a03439adb92b319f3af53dd1d0", "tree": "56a88401a218622018030045fec009bafdc4ce76", "parents": [ "3a8a9a1034813aa99f5ae3150f652d490c5ff10d" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 16:25:27 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 16:25:27 2006 -0400" }, "message": "[GFS2] glock debugging and inode cache changes\n\nThis adds some extra debugging to glock.c and changes\ninode.c\u0027s deallocation code to call the debugging code\nat a suitable moment.
