There should be a short explanation what the patch does, eg.
"use helper for open coded kmap_atomic/memcpy/kunmap_atomic",
although I see there are conversions kmap_atomic -> kmap_local not in
the coccinelle script, probably done manually. This should be mentioned
too.

Also please use "btrfs:" followed by lowercase in the subject.
