The problem is that for \"normal\"\nalloc/dealloc, we always grab the inode locks first and the rgrp lock\nlater.\n\nIn order to ensure no races in looking up the unlinked, but still\nallocated inodes, we need to hold the rgrp lock when we do the lookup,\nwhich means that we can\u0027t take the inode glock.\n\nThe solution is to borrow the technique already used by NFS to solve\nwhat is essentially the same problem (given an inode number, look up\nthe inode carefully, checking that it really is in the expected\nstate).\n\nWe cannot do that directly from the allocation code (lock ordering\nagain) so we give the job to the pre-existing delete workqueue and\ncarry on with the allocation as normal.\n\nIf we find there is no space, we do a journal flush (required anyway\nif space from a deallocation is to be released) which should block\nagainst the pending deallocations, so we should always get the space\nback.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "1ca7318cacdac5262492149cf46abc06c95693fa", "tree": "c8532b1cd52ab4858a7550b8e2dd0cb1f5a1eb03", "parents": [ "0143832cc96d0bf78486297aad5c8fb2c2ead02a", "1c66b360fe26204e2aa14e45086b4a6b8890b1a2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Nov 14 13:04:53 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Nov 14 13:04:53 2010 -0800" }, "message": "Merge branch \u0027upstream-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2\n\n* \u0027upstream-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2:\n ocfs2: Change some lock status member in ocfs2_lock_res to char.\n" }, { "commit": "1c66b360fe26204e2aa14e45086b4a6b8890b1a2", "tree": "d2608809e0985e4aff7bdc9f5673a8c39d7eb916", "parents": [ "2d3b07c07b39c4b7d9b6641052a02d996cd5d87c" ], "author": { "name": "Tao Ma", "email": "tao.ma@oracle.com", "time": "Sat Nov 13 16:22:02 2010 +0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Sat Nov 13 03:15:08 2010 -0800" }, "message": "ocfs2: Change some lock status member in ocfs2_lock_res to char.\n\nCommit 83fd9c7 changes l_level, l_requested and l_blocking of\nocfs2_lock_res from int to unsigned char.
