2008-09-25Btrfs: Clone file data ioctlSage Weil1-6/+6
Add a new ioctl to clone file data Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Write bio checksumming outside the FS mutexChris Mason1-14/+32
This significantly improves streaming write performance by allowing concurrency in the data checksumming. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: checksum file data at bio submission time instead of during writepageChris Mason1-11/+39
When we checkum file data during writepage, the checksumming is done one page at a time, making it difficult to do bulk metadata modifications to insert checksums for large ranges of the file at once. This patch changes btrfs to checksum on a per-bio basis instead. The bios are checksummed before they are handed off to the block layer, so each bio is contiguous and only has pages from the same inode. Checksumming on a bio basis allows us to insert and modify the file checksum items in large groups. It also allows the checksumming to be done more easily by async worker threads.

2008-09-25Btrfs: Fix a number of inline extent problems that Yan Zheng reported.Chris Mason1-1/+1
The fixes do a number of things: 1) Most btrfs_drop_extent callers will try to leave the inline extents in place. It can truncate bytes off the beginning of the inline extent if required. 2) writepage can now update the inline extent, allowing mmap writes to go directly into the inline extent. 3) btrfs_truncate_in_transaction truncates inline extents 4) extent_map.c fixed to not merge inline extent mappings and hole mappings together Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Minor fix for btrfs_csum_file_block.Yan1-6/+4
Execution should goto label 'insert' when 'btrfs_next_leaf' return a non-zero value, otherwise the parameter 'slot' for 'btrfs_item_key_to_cpu' may be out of bounds. The original codes jump to label 'insert' only when 'btrfs_next_leaf' return a negative value. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Optimize csum insertion to create larger items when possibleChris Mason1-1/+36
This reduces the number of calls to btrfs_extend_item and greatly lowers the cpu usage while writing large files. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2007-07-11Btrfs: trivial include fixupsZach Brown1-1/+0
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>

2007-06-14btrfs: Code cleanupAneesh1-2/+0
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>
