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.

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>

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>

The end_bio routines are changed to take a pointer to the extent state struct, and the state tree is walked in order to set/clear appropriate bits as IO completes. This greatly reduces the number of rbtree searches done by the end_bio handlers, and reduces lock contention. The extent_io releasepage function is changed to avoid expensive searches for locked state. Signed-off-by: NChris Mason <chris.mason@oracle.com>

There is now extent_map for mapping offsets in the file to disk and extent_io for state tracking, IO submission and extent_bufers. The new extent_map code shifts from [start,end] pairs to [start,len], and pushes the locking out into the caller. This allows a few performance optimizations and is easier to use. A number of extent_map usage bugs were fixed, mostly with failing to remove extent_map entries when changing the file. Signed-off-by: NChris Mason <chris.mason@oracle.com>

There were a few places that could cause duplicate extent insertion, this adjusts the code that creates holes to avoid it. lookup_extent_map is changed to correctly return all of the extents in a range, even when there are none matching at the start of the range.

test_range_bit doesn't properly handle the case: there's a hole at the end of the range and there's no other extent_state after the range. Signed-off-by: NChris Mason <chris.mason@oracle.com>

This is intended to prevent accidentally filling the drive. A determined user can still make things oops. It includes some accounting of the current bytes under delayed allocation, but this will change as things get optimized Signed-off-by: NChris Mason <chris.mason@oracle.com>

The attached patch fixes this for me. Not sure if it is correct though.

There is a 'finish_wait', but no 'prepare_to_wait' . So I think that the 'prepare_to_wait' is missing. The second change is according to the name of variable. Signed-off-by: NChris Mason <chris.mason@oracle.com>
