Chris Mason 6af118ce51 Btrfs: Index extent buffers in an rbtree ... Before, extent buffers were a temporary object, meant to map a number of pages at once and collect operations on them. But, a few extra fields have crept in, and they are also the best place to store a per-tree block lock field as well. This commit puts the extent buffers into an rbtree, and ensures a single extent buffer for each tree block. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2008-09-25 11:04:05 -04:00
