The first change removes potential double free, the second fix a off by one error. Signed-off-by: -

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: -

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: -

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: -

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:

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: -

Dead roots are trees left over after a crash, and they were either in the process of being removed or were waiting to be removed when the box crashed. Before, a search of the entire tree of root pointers was done on mount looking for dead roots. Now, the search is done the first time we load a root. This makes mount faster when there are a large number of snapshots, and it enables the block accounting code to properly update the block counts on the latest root as old versions of the root are reaped after a crash.

XFS updates the ondisk inode size only after the data I/O has finished, so it needs a hook when the writepage end_bio handler has finished. Might not be worth applying as-is as the per-page callback is very ineffcient. What XFS really wants is a callback when writeout of a whole extent has completed. This delayed i_size updates scheme might be worthwile for btrfs aswell, btw. Signed-off-by:

The writepage_io is not mandatory, e.g. my port of xfs to the extent_map code does not have one for now. So handle a NULL pointer gracefully here. Signed-off-by:
