Probably, but I guess Darrick has those in his TODO.

There is this series that refers to failure in generic/232:
https://marc.info/?l=linux-xfs&m=151701545720824&w=2

These 2 commits refer to generic/269 specifically in commit message:
 70c57dcd606f xfs: skip CoW writes past EOF when writeback races with truncate
 be78ff0e7277 xfs: recheck reflink / dirty page status before freeing
CoW reservations
and the thread on the second commit also mentions generic/270
(I found out the hard way that it also soft locks).

But there are surely more patches for stable in master.
I recon CC: stable and/or Fixes: tags could have been helpful,
but I don't see any of those in v4.16-rcX from the core xfs developers.

Cheers,
Amir.
