2008-09-25Btrfs: Add some simple throttling to wait for data=ordered and snapshot deletionChris Mason1-0/+1

2008-09-25Btrfs: Add data=ordered supportChris Mason1-0/+2
This forces file data extents down the disk along with the metadata that references them. The current implementation is fairly simple, and just writes out all of the dirty pages in an inode before the commit. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: Use balance_dirty_pages_nr on btree blocksChris Mason1-1/+1
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>

2007-08-28Btrfs: Extent based page cache code. This uses an rbtree of extents and testsChris Mason1-1/+0
instead of buffer heads. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-10Btrfs: Add BH_Defrag to mark buffers that are in need of defraggingChris Mason1-0/+2
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. Signed-off-by: Chris Mason <chris.mason@oracle.com>
