Given the potential severity of the bug, I think it deserves a somewhat
richer explanation than just that. It should also go into stable. This
is what I queued up:
https://git.kernel.dk/cgit/linux-block/commit/?h=block-5.5&id=add1fc07334260253dfa880d9c964edc8381deac
BTW, did you change your email setup recently? Your patches are coming
through mangled.
