I'd rather not add a sixth argument to do_read_cache_folio().

And I'm not sure the right question is being asked here.  Storage can
disappear at any moment -- somebody unplugs the USB device, the NBD
device that's hosting the filesystem experiences a network outage, etc.

So every filesystem _should_ handle fatal signals gracefully.  The task
must die, even if it's in the middle of reading metadata.  I know that's
not always the easiest thing to do, but it is the right thing to do.
