Yes.  a) really isn't an option - we don't want to spew thousands of
useless messages during a log recovery for an operation that's totally
normal.  b) is okay, too - but it's not just xfs that needs to be
covered, but any fs that support the concept of recovering from open
but unlinked inodes after a crash.  It's just that no one else seems
to have regular QA for that code path.
