I converted btrfs_truncate to do sane reservations for truncate, but didn''t convert btrfs_evict_inode. Basically we need to save the orphan_rsv for deleting the orphan item, and do normal reservations for our truncate.

The freeze rwsem is taken by sb_start_intwrite() and dropped during the commit_ or end_transaction(). In the async case, that happens in a worker thread. Tell lockdep the calling thread is releasing ownership of the rwsem and the async thread is picking it up. Josef and I worked out a more complicated solution that made the async commit thread join and potentially get a later transaction, but

...t in a commit, that is, inode.c:btrfs_orphan_commit_root() doesn''t get called (via transaction.c:commit_fs_roots()). The respective inode will end up being called by inode.c:btrfs_evict_node() (via the VFS). So my likely dirty hack, after some debugging, of freeing the orphan block rsv in btrfs_evict_inode() if its not being used by other tasks, seems to fix the leak without failing xfstests so far. But this is unlikely to be a correct solution without causing issues elsewhere. This commit also changes calls to btrfs_orphan_del() which grabbed the root''s orphan_block_rsv without acquiring t...

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

Hello, I have a 5.5TB Btrfs filesystem on top of a md-raid 5 device. Now if i run some file operations like find, i get these messages. kernel is 2.6.38.5-1 on arch linux May 5 14:15:12 mail kernel: [13559.089713] parent transid verify failed on 3062073683968 wanted 5181 found 5188 May 5 14:15:12 mail kernel: [13559.089834] parent transid verify failed on 3062073683968 wanted 5181 found 5188

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.
