As a part of reaping, the container-init should flush any /proc\ndentries associated with the processes. But because the container-init is\nitself exiting and the following PF_EXITING check, the dentries are not\nflushed, resulting in leak in /proc inodes and dentries.\n\nThis fix reverts the commit 7766755a2f249e7e0 (\"Fix /proc dcache deadlock\nin do_exit\") which introduced the check for PF_EXITING. At the time of\nthe commit, shrink_dcache_parent() flushed dentries from other filesystems\nalso and could have caused a deadlock which the commit fixed. But as\npointed out by Eric Biederman, after commit 0feae5c47aabdde59,\nshrink_dcache_parent() no longer affects other filesystems.

Hopefully the comments are helpfull, but\nI\u0027ll try and be as verbose here.\n\nProblem:\n\nMy fedora box was taking 1 minute and 21 seconds to boot with btrfs as root.\nPart of this problem was we pick the first block group we can find and start\ncaching it, even if it may not have enough free space. The other problem is\nwe only search for cached block groups the first time around, which we won\u0027t\nfind any cached block groups because this is a newly mounted fs, so we end up\ncaching several block groups during bootup, which with alot of fragmentation\ntakes around 30-45 seconds to complete, which bogs down the system. So\n\nSolution:\n\n1) Don\u0027t cache block groups willy-nilly at first. Instead try and figure out\nwhich block group has the most free, and therefore will take the least amount\nof time to cache.\n\n2) Don\u0027t be so picky about cached block groups. The other problem is once\nwe\u0027ve filled up a cluster, if the block group isn\u0027t finished caching the next\ntime we try and do the allocation we\u0027ll completely ignore the cluster and\nstart searching from the beginning of the space, which makes us cache more\nblock groups, which slows us down even more. So instead of skipping block\ngroups that are not finished caching when we have a hint, only skip the block\ngroup if it hasn\u0027t started caching yet.\n\nThere is one other tweak in here. Before if we allocated a chunk and still\ncouldn\u0027t find new space, we\u0027d end up switching the space info to force another\nchunk allocation. This could make us end up with way too many chunks, so keep\ntrack of this particular case.\n\nWith this patch and my previous cluster fixes my fedora box now boots in 43\nseconds, and according to the bootchart is not held up by our block group\ncaching at all.\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "4eb3991c5def39bcf553c14ebe2618fcb47b627f", "tree": "9c35f532bd29e68014cc16dc6e528a8cca5cfe34", "parents": [ "df66916e71231e9f2377cac9c5c1e2d190f9a427" ], "author": { "name": "Dan Carpenter", "email": "error27@gmail.com", "time": "Tue Nov 10 09:01:43 2009 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Nov 11 14:20:18 2009 -0500" }, "message": "Btrfs: avoid null deref in unpin_extent_cache()\n\nI re-orderred the checks to avoid dereferencing \"em\" if it was null.\n\nFound by smatch static checker.\n\nSigned-off-by: Dan Carpenter \u003cerror27@gmail.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "df66916e71231e9f2377cac9c5c1e2d190f9a427", "tree": "9668d3ca20bf6c0b4187f272d85aa026f0a06121", "parents": [ "5df6a9f606bf2ee25ab8031bff124ed883b823be" ], "author": { "name": "Li Dongyang", "email": "jerry87905@gmail.com", "time": "Fri Nov 06 14:33:01 2009 +0000" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Nov 11 14:20:18 2009 -0500" }, "message": "Btrfs: skip btrfs_release_path in btrfs_update_root and btrfs_del_root\n\nWe don\u0027t need to call btrfs_release_path because btrfs_free_path will do\nthat for us.\n\nSigned-off-by: Li Dongyang \u003cJerry87905@gmail.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "5df6a9f606bf2ee25ab8031bff124ed883b823be", "tree": "2492876b6ebd9c4c52a50de1a431285fe3779889", "parents": [ "01dea1efc23b511d3b58bb94da07ddb6d6db9895" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Tue Nov 10 21:23:48 2009 -0500" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Nov 11 14:20:17 2009 -0500" }, "message": "Btrfs: fix some metadata enospc issues\n\nWe weren\u0027t reserving metadata space for rename, rmdir and unlink, which could\ncause problems.\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "01dea1efc23b511d3b58bb94da07ddb6d6db9895", "tree": "4112505e90ab22936f4de18e15197979dd176cdc", "parents": [ "249ac1e55c642c670f47aacdc57629bbbf10a8db" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Tue Nov 10 21:23:48 2009 -0500" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Nov 11 14:20:17 2009 -0500" }, "message": "Btrfs: fix how we set max_size for free space clusters\n\nThis patch fixes a problem where max_size can be set to 0 even though we\nfilled the cluster properly. We set max_size to 0 if we restart the cluster\nwindow, but if the new start entry is big enough to be our new cluster then we\ncould return with a max_size set to 0, which will mean the next time we try to\nallocate from this cluster it will fail. So set max_extent to the entry\u0027s\nsize. Tested this on my box and now we actually allocate from the cluster\nafter we fill it.
