[PATCHSET] xfs: LLM-inspired bug fixes, part 4

Hi all,

Here's a fourth batch of xfs fixes resulting from a LLaMma.  Mwa mwa
mwa...

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

With a bit of luck, this should all go splendidly.
Comments and questions are, as always, welcome.
