The goal here is to make truncate more generic and\nstraightforward.\n\nSeveral functions only used by ocfs2_commit_truncate() will smiply be\nremoved.\n\nocfs2_remove_btree_range() was originally used by the hole punching\ncode, which didn\u0027t take refcount trees into account (definitely a bug).\nWe therefore need to change that func a bit to handle refcount trees.\nIt must take the refcount lock, calculate and reserve blocks for\nrefcount tree changes, and decrease refcounts at the end. We replace \nocfs2_lock_allocators() here by adding a new func\nocfs2_reserve_blocks_for_rec_trunc() which accepts some extra blocks to\nreserve. This will not hurt any other code using\nocfs2_remove_btree_range() (such as dir truncate and hole punching).\n\nI merged the following steps into one patch since they may be\nlogically doing one thing, though I know it looks a little bit fat\nto review.\n\n1). Remove redundant code used by ocfs2_commit_truncate(), since we\u0027re\n moving to ocfs2_remove_btree_range anyway.\n\n2). Add a new func ocfs2_reserve_blocks_for_rec_trunc() for purpose of\n accepting some extra blocks to reserve.\n\n3). Change ocfs2_prepare_refcount_change_for_del() a bit to fit our\n needs. It\u0027s safe to do this since it\u0027s only being called by\n truncate.\n\n4). Change ocfs2_remove_btree_range() a bit to take refcount case into\n account.\n\n5). Finally, we change ocfs2_commit_truncate() to call\n ocfs2_remove_btree_range() in a proper way.\n\nThe patch has been tested normally for sanity check, stress tests\nwith heavier workload will be expected.\n\nBased on this patch, fixing the punching holes bug will be fairly easy.\n\nSigned-off-by: Tristan Ye \u003ctristan.ye@oracle.com\u003e\nAcked-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "83f92318fa33cc084e14e64dc903e605f75884c1", "tree": "c7466c64019fb050c69cab27b4388e3a86d58b1a", "parents": [ "b07f8f24dfe54da0f074b78949044842e8df881f" ], "author": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Apr 05 18:17:16 2010 -0700" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Wed May 05 18:18:07 2010 -0700" }, "message": "ocfs2: Add dir_resv_level mount option\n\nThe default behavior for directory reservations stays the same, but we add a\nmount option so people can tweak the size of directory reservations\naccording to their workloads.\n\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "e3b4a97dbe9741a3227c3ed857a0632532fcd386", "tree": "31da8dd09ad6ef8959b287e36e98ead30472a284", "parents": [ "4fe370afaae49c57619bb0bedb75de7e7c168308" ], "author": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Dec 07 13:16:07 2009 -0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Wed May 05 18:17:30 2010 -0700" }, "message": "ocfs2: use allocation reservations for directory data\n\nUse the reservations system for unindexed dir tree allocations.
