Hi Phil,
You should probably cc the relevant lists with such patchsets so the

When you quote a commit, short form followed by the name (i.e.
one-line form) is preferable because it gives context to the commit
without needing to go look it up in a git tree. Commit IDs are not
human readable, while commit log should be.
The commit in question - ff57ab2 ("xfs: convert xfsbud shrinker to a
per-buftarg shrinker.") - removed the list but the code being
removed was already long dead. FWIW, I know just by reading the
commit description when the list went away and who was responsible
for missing that. i.e. me. ;)

Not necessary in a commit description - the zero patch of a series,
yes, to describe how the issues were found, but it doesn't need to
be recorded forever in the commit log. ;)

Code changes look good. Can you fix the commit description and
resend to xfs@xxxxxxxxxxx?
Cheers,
Dave.
