     Yes, it is — same root cause and effectively the same verifier check.
     My dedup search was limited to torvalds/linux.git (lore and
     git.kernel.org are unreachable from my test environment), so I missed
     Aldo's series. Sorry for the noise.

     His series looks correct to me, and the 1/2 change to
     xfs_attr_copy_value() closes the signedness bypass at the
     consumption site as well, which my patch did not touch.

     Thanks,
     Miao
