2007-09-14Btrfs: use unlocked_ioctlChristoph Hellwig1-4/+1
No reason to grab the BKL before calling into the btrfs ioctl code. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-09-11Btrfs: Find and remove dead roots the first time a root is loaded.Chris Mason1-1/+2
Dead roots are trees left over after a crash, and they were either in the process of being removed or were waiting to be removed when the box crashed. Before, a search of the entire tree of root pointers was done on mount looking for dead roots. Now, the search is done the first time we load a root. This makes mount faster when there are a large number of snapshots, and it enables the block accounting code to properly update the block counts on the latest root as old versions of the root are reaped after a crash.

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: Use mount -o subvol to select the subvol directory instead of dev:Chris Mason1-0/+6

2007-08-28Btrfs: Extent based page cache code. This uses an rbtree of extents and testsChris Mason1-0/+7
instead of buffer heads. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-11Btrfs: delay commits during fsync to allow more writersJosef Bacik1-0/+1

2007-08-09Btrfs: Replace extent tree preallocation code with some bit radix magic.Chris Mason1-6/+1

2007-08-08Btrfs: Let some locks go during defrag and snapshot droppingChris Mason1-2/+2
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-08Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason1-2/+17
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>
2007-08-07Btrfs: Fold some btree readahead routines into something more generic.Chris Mason1-0/+1
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-07Btrfs: Do snapshot deletion in smaller chunks.Chris Mason1-2/+2
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>

2007-06-26Btrfs: Fix super block updates during transaction commitChris Mason1-0/+1
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>
