* Btrfs: Create extent_buffer interface for large blocksizesChris Mason2008-09-25
| | | | Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: Use balance_dirty_pages_nr on btree blocksChris Mason2008-09-25
| | | | | | | | btrfs_btree_balance_dirty is changed to pass the number of pages dirtied for more accurate dirty throttling. This lets the VM make better decisions about when to force some writeback. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: Find and remove dead roots the first time a root is loaded.Chris Mason2007-09-11
| | | | | | | | | | | | | | 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.

* Btrfs: Add more synchronization before creating a snapshotChris Mason2007-09-10
| | | | | | | | 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>

* Btrfs: Replace extent tree preallocation code with some bit radix magic.Chris Mason2007-08-08

* Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason2007-08-07
| | | | | | | | | | | 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: trivial include fixupsZach Brown2007-07-11
| | | | | | | | | | | 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 Mason2007-06-26
| | | | | | | | 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>
