* Btrfs: Various small fixes.Yan Zheng2008-09-251-2/+1
| | | | | | | | This trivial patch contains two locking fixes and a off by one fix. --- Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: Fix deadlock while searching for dead roots on mountChris Mason2008-09-251-1/+9
| | | | | | | | | | btrfs_find_dead_roots called btrfs_read_fs_root_no_radix, which means we end up calling btrfs_search_slot with a path already held. The fix is to remember the key inside btrfs_find_dead_roots and drop the path. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Find and remove dead roots the first time a root is loaded.Chris Mason2007-09-111-3/+13
| | | | | | | | | | | | | | Dead roots are trees left over after a crash, and they were either in the process of being removed or were waiting to be removed when the box crashed. Before, a search of the entire tree of root pointers was done on mount looking for dead roots. Now, the search is done the first time we load a root. This makes mount faster when there are a large number of snapshots, and it enables the block accounting code to properly update the block counts on the latest root as old versions of the root are reaped after a crash.

* Btrfs: trivial include fixupsZach Brown2007-07-111-1/+0
| | | | | | | | | | | Almost none of the files including module.h need to do so, remove them. Include sched.h in extent-tree.c to silence a warning about cond_resched() being undeclared. Signed-off-by: Zach Brown <zach.brown@oracle.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>

| | | | | | | | | | | Attaching below is some of the code cleanups that i came across while reading the code. a) alloc_path already calls init_path. b) Mention that btrfs_inode is the in memory copy.Ext4 have ext4_inode_info as the in memory copy ext4_inode as the disk copy Signed-off-by: Chris Mason <chris.mason@oracle.com>
