Chris Mason	6702ed490c	Btrfs: Add run time btree defrag, and an ioctl to force btree defrag ... This adds two types of btree defrag, a run time form that tries to defrag recently allocated blocks in the btree when they are still in ram, and an ioctl that forces defrag of all btree blocks. File data blocks are not defragged yet, but this can make a huge difference in sequential btree reads. Signed-off-by: Chris Mason <chris.mason@oracle.com>	2007-08-07 16:15:09 -04:00
