Btrfs: reduce extent_state lock contention for metadata For metadata buffers that don't straddle pages (all of them), btrfs can safely use the page uptodate bits and extent_buffer uptodate bit instead of needing to use the extent_state tree. This greatly reduces contention on the state tree lock. Signed-off-by: Chris Mason <chris.mason@oracle.com>
