2007-09-11Btrfs: Add more synchronization before creating a snapshotChris Mason1-0/+1
File data checksums are only done during writepage, so we have to make sure all pages are written when the snapshot is taken. This also adds some locking so that new writes don't race in and add new dirty pages. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-29Btrfs: Add per-root block accounting and sysfs entriesJosef Bacik1-2/+29

2007-08-08Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason1-0/+8
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>
2007-07-11Btrfs: trivial include fixupsZach Brown1-1/+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>

2007-06-26Btrfs: Fix super block updates during transaction commitChris Mason1-3/+2
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>
