2008-09-25Btrfs: Create extent_buffer interface for large blocksizesChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-09-10Add support for defragging files via btrfsctl -d. Avoid OOM on extent treeChris Mason
defrag. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-29Btrfs: ctree.c cleanupsYan
Fixup a few buffer_head release errors, and fix an off by one in balance_node_right. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-27Btrfs: Do more extensive readahead during tree searchesChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-27fix block readahead in btrfs_next_leafYan
Send the correct slot down to reada_for_search Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-10Btrfs: Add BH_Defrag to mark buffers that are in need of defraggingChris Mason
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>
2007-08-10Btrfs: Btree defrag on the extent-mapping tree as wellChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-07Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason
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 Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-07Btrfs: Do snapshot deletion in smaller chunks.Chris Mason
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>

Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-07-11Btrfs: trivial include fixupsZach Brown
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>

2007-06-13btrfs: Code cleanupAneesh
Attaching below is some of the code cleanups that i came across while reading the code. a) alloc_path already calls init_path. b) Mention that btrfs_inode is the in memory copy.Ext4 have ext4_inode_info as the in memory copy ext4_inode as the disk copy Signed-off-by: Chris Mason <chris.mason@oracle.com>
