Chris Mason	86479a04ee	Add support for defragging files via btrfsctl -d. Avoid OOM on extent tree ... defrag. Signed-off-by: Chris Mason <chris.mason@oracle.com>	18 years ago
Chris Mason	f2183bde1a	Btrfs: Add BH_Defrag to mark buffers that are in need of defragging ... This allows the tree walking code to defrag only the newly allocated buffers, it seems to be a good balance between perfect defragging and the performance hit of repeatedly reallocating blocks.

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>	18 years ago
