Here is an assortment of fixes, mainly around the async (compressed) cow path.
Just removes some redundant arguments/local variables, makes shrink_delalloc a
bit more readable by simplifying variable usage and giving more appropriate names.
Also documents the ->inode null check in async_cow_submit and cleans up open-coded
usage of DIV_ROUND_UP. No functional changes to any of the patches.

Nikolay Borisov (7):
btrfs: Remove inode argument from async_cow_submit
btrfs: Remove isize local variable in compress_file_range
btrfs: Use ihold instead of igrab in cow_file_range_async
btrfs: Remove WARN_ON in btrfs_alloc_delalloc_work
btrfs: Document logic in async_cow_submit
btrfs: Replace open-coded maths with DIV_ROUND_UP
btrfs: Refactor shrink_delalloc
