For all of these, I was under the impression that the SHA1 of commits in
Andrew's trees were not stable and could change.  That is why I purposely
did not try to add SHA1s to the tags.  Perhaps that is no longer the case
since Andrew is using git to manage patches?

I see that a pull request including these commits was already sent to
Linus.  Not sure where these are in the process, or if it may be too
late to update.  Let me know if there is anything I can do.

I assume that once a commit is in the mm-stable branch of Andrew's tree
that the SHA1 will be fixed (except in exceptional circumstances).
Andrew?

Yeah, I saw that, and as you say, we must just have to live with these.

My fault.

It should be "mm/migration", NOT "mm: migration "

Fixes: 4cd614841c06 ("mm/migration: fix possible do_pages_stat_array racing with memory offline")

Should I send new patch ?

Nope.  I fix things like that.

But in this case I don't think I'll bother.  The world won't end.

Thanks, Stephen.
