2008-09-25Call btrfs_cow_block while lowering tree level.Yan
When freeing root block of a tree, btrfs_free_extent' parameter 'ref_generation' is from root block itseft. When freeing non-root block, 'ref_generation' is from its parent. so when converting a non-root block to root block, we must guarantee its generation is equal to its parent's generation.

2008-09-25Btrfs: Hash in the offset and owner for file extent backref keysChris Mason
This makes searches for backrefs and backref insertion much more efficient when there are many backrefs for a single extent Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25btrfs_drop_extent fixe for inline items > 8KYan
When truncating a inline extent, btrfs_drop_extents doesn't properly handle the case "key.offset > inline_limit". This bug can only happen when max line size is larger than 8K. Signed-off-by: Chris Mason <chris.mason@oracle.com>

Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: extent_io and extent_state optimizationsChris Mason
The end_bio routines are changed to take a pointer to the extent state struct, and the state tree is walked in order to set/clear appropriate bits as IO completes. This greatly reduces the number of rbtree searches done by the end_bio handlers, and reduces lock contention. The extent_io releasepage function is changed to avoid expensive searches for locked state. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Add some extra debugging around file data checksum failuresChris Mason

Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Split the extent_map code into two partsChris Mason
There is now extent_map for mapping offsets in the file to disk and extent_io for state tracking, IO submission and extent_bufers. The new extent_map code shifts from [start,end] pairs to [start,len], and pushes the locking out into the caller. This allows a few performance optimizations and is easier to use. A number of extent_map usage bugs were fixed, mostly with failing to remove extent_map entries when changing the file. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix hole insertion corner casesChris Mason
There were a few places that could cause duplicate extent insertion, this adjusts the code that creates holes to avoid it. lookup_extent_map is changed to correctly return all of the extents in a range, even when there are none matching at the start of the range.

2008-09-25Btrfs: Include sched.h in the acl code for current (fixes compile on 2.6.23)Chris Mason

2008-09-25Btrfs: Fix for test_range_bitYan
test_range_bit doesn't properly handle the case: there's a hole at the end of the range and there's no other extent_state after the range. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Fix for btrfs_find_free_objectidYan
btrfs_find_free_objectid may return a used objectid due to arithmetic underflow. This bug may happen when parameter 'root' is tree root, so it may cause serious problems when creating snapshot or sub-volume. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: Fix data=ordered vs wait_on_inode deadlock on older kernelsChris Mason
Using ilookup5 during data=ordered writeback could deadlock on I_LOCK. This saves a pointer to the inode instead. Signed-off-by: Chris Mason <chris.mason@oracle.com>
