2008-09-25Btrfs: Fix extent_buffer and extent_state leaksChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Create extent_buffer interface for large blocksizesChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix duplicate ENOSPC checks in find_free_extentChris Mason
find_free_extent would fail to wrap around to the start of the drive because it was doing the enospc case checking twice in some cases, causing it to return -ENOSPC early. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Use balance_dirty_pages_nr on btree blocksChris Mason
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>
2007-09-14Btrfs: Fix cache_block_group to catch holes at the start of the groupYan
Cache block group was overly complex and missed free blocks at the very start of the group. This patch simplifies things significantly. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-29Btrfs: Fix oopsen in extent_tree.c during enospcYan
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-29Btrfs: Add per-root block accounting and sysfs entriesJosef Bacik
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-27Btrfs: Add delayed allocation to the extent based page tree codeChris Mason
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>
2007-08-10Btrfs: 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>
2007-08-08Btrfs: Further reduce the concurrency penalty of defrag and drop_snapshotChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-08Btrfs: Replace extent tree preallocation code with some bit radix magic.Chris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-08-08Btrfs: Let some locks go during defrag and snapshot droppingChris 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>
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>

2007-06-26Btrfs: Allow find_free_extent callers to pass in an exclusion rangeChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-06-26Btrfs: Fix super block updates during transaction commitChris Mason
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>
2007-06-22Btrfs: Audit callers and return codes to make sure -ENOSPC gets up the stackChris Mason

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>
