2008-09-25Btrfs: Add back metadata checksummingChris Mason

2008-09-25Btrfs: Allow tree blocks larger than the page sizeChris Mason

2008-09-25btrfs_get_extent should treat inline extents as though they hold a whole blockChris Mason

2008-09-25Btrfs: factor page private preparations into a helperChristoph Hellwig
Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix double free and off by one in inode.cYan
The first change removes potential double free, the second fix a off by one error. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: truncate: don't update inode->i_blocks when extent is a holeYan
I think check whether extent is a hole before update 'inode->i_blocks' is unconditional required. (original codes check it only when del_item isn't equal to 0) Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25create btrfs_path slab with the correct sizeYan
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25fix found_type decrement in btrfs_truncate_in_transYan
found_type has already been decreased by codes above the change, I think decrease it by one again doesn't make sense. 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>
2007-09-14split up btrfs_ioctlChristoph Hellwig
Add a helper per ioctl function to make the code more readable. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-09-14Btrfs: use unlocked_ioctlChristoph Hellwig
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>
2007-09-14Btrfs: Fix extra link count dec in renameChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-09-10Btrfs: [PATCH] extent_map: provide generic bmapChristoph Hellwig
generic_bmap is completely trivial, while the extent to bh mapping in btrfs is rather complex. So provide a extent_bmap instead that takes a get_extent callback and can be used by filesystem using the extent_map code. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2007-09-10Btrfs: Add more synchronization before creating a snapshotChris Mason
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>
2007-09-10Add support for defragging files via btrfsctl -d. Avoid OOM on extent treeChris Mason

2007-08-27Btrfs: Add delayed allocation to the extent based page tree codeChris Mason
Signed-off-by: Chris Mason <chris.mason@oracle.com>

2007-08-10Btrfs: 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>

2007-07-11Btrfs: 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>
