Here's a patch against the unstable tree that gets the code to build against Linus's current tree (2.6.24-git12). This is needed as the kobject/kset api has changed there. I tried to make the smallest changes needed, and it builds and loads successfully, but I don't have a btrfs volume anywhere (yet) to try to see if things still work properly :) Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de> Signed-off-by: NChris Mason <chris.mason@oracle.com>

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.

Yan Zheng noticed that we don't clear the extent state tree dirty and delalloc bits when we clear the dirty bits on the page during file write. This leads to csum errors later on. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Reduce CPU time searching for free blocks by optimizing find_first_extent_bit Fix find_free_extent to make better use of the last_alloc hint. Before it was often finding blocks just before the hint. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Btrfs set/get macros lose type information needed to avoid unaligned accesses on sparc64. ere is a patch for the kernel bits which fixes most of the unaligned accesses on sparc64. btrfs_name_hash is modified to return the hash value instead of getting a return location via a (potentially unaligned) pointer.

A few codes were not properly updated for changes of extent map. This may be the causes of "no csum found for inode" issue. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Now that delayed allocation accounting works, i_blocks accounting is changed to only modify i_blocks when extents inserted or removed. The fillattr call is changed to include the delayed allocation byte count in the i_blocks result. Signed-off-by: NChris Mason <chris.mason@oracle.com>

When freeing root block of a tree, btrfs_free_extent' parameter 'ref_generation' is from root block itseft. When freeing non-root block, 'ref_generation' is from its parent. so when converting a non-root block to root block, we must guarantee its generation is equal to its parent's generation.

When truncating a inline extent, btrfs_drop_extents doesn't properly handle the case "key.offset > inline_limit". This bug can only happen when max line size is larger than 8K. Signed-off-by: NChris Mason <chris.mason@oracle.com>
