* Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason2007-08-071-18/+87
| | | | | | | | | | | 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>
* Btrfs: Do snapshot deletion in smaller chunks.Chris Mason2007-08-071-25/+38
| | | | | | | | | Before, snapshot deletion was a single atomic unit. This caused considerable lock contention and required an unbounded amount of space. Now, the drop_progress field in the root item is used to indicate how far along snapshot deletion is, and to resume where it left off. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: trivial include fixupsZach Brown2007-07-111-1/+0
| | | | | | | | | | | Almost none of the files including module.h need to do so, remove them. Include sched.h in extent-tree.c to silence a warning about cond_resched() being undeclared. Signed-off-by: Zach Brown <zach.brown@oracle.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Fix super block updates during transaction commitChris Mason2007-06-261-2/+6
| | | | | | | | The super block written during commit was not consistent with the state of the trees. This change adds an in-memory copy of the super so that we can make sure to write out consistent data during a commit. Signed-off-by: Chris Mason <chris.mason@oracle.com>
