This causes problems during umount because ocfs2_wq\ncan drop references to inodes while they are being invalidated by\ninvalidate_inodes() causing all sorts of nasty things (invalidate_inodes()\nending in an infinite loop, \"Busy inodes after umount\" messages etc.).\n\nWe fix the problem by stopping ocfs2_wq from doing any further releasing of\ninode references on the superblock being unmounted, wait until it finishes\nthe current round of releasing and finally cleaning up all the references in\ndentry_lock_list from ocfs2_put_super().\n\nThe issue was tracked down by Tao Ma \u003ctao.ma@oracle.com\u003e.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "3c5e10683e684ef45614c9071847e48f633d9806", "tree": "2861ea95385422c50afc818dd6bb2d2c6cb9d46a", "parents": [ "1f4cea3790bf44137192f441ee84af256e3bf809" ], "author": { "name": "Tao Ma", "email": "tao.ma@oracle.com", "time": "Tue Jul 21 15:42:05 2009 +0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Jul 21 14:41:54 2009 -0700" }, "message": "ocfs2: Add extra credits and access the modified bh in update_edge_lengths.\n\nIn normal tree rotation left process, we will never touch the tree\nbranch above subtree_index and ocfs2_extend_rotate_transaction doesn\u0027t\nreserve the credits for them either.\n\nBut when we want to delete the rightmost extent block, we have to update\nthe rightmost records for all the rightmost branch(See\nocfs2_update_edge_lengths), so we have to allocate extra credits for them.\nWhat\u0027s more, we have to access them also.\n\nSigned-off-by: Tao Ma \u003ctao.ma@oracle.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "1f4cea3790bf44137192f441ee84af256e3bf809", "tree": "64c83d47e0ea24f14b0237d9d63426e7e5af9227", "parents": [ "cbfa9639aea5007313b75ec43b689d5f9e0c037d" ], "author": { "name": "Wengang Wang", "email": "wen.gang.wang@oracle.com", "time": "Mon Jul 13 11:38:58 2009 +0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Mon Jul 20 17:36:07 2009 -0700" }, "message": "ocfs2: Fail ocfs2_get_block() immediately when a block needs allocation\n\nocfs2_get_block() does no allocation.
