You'll get an OK for me as I'd like this series in 3.7, but I'd really
prefer if we could stop waking up xfsaild from here ASAP, and instead
just do a schedule_timeout in xfsaild where we currently sleep forever.

Any chance to get a follow on patch for that?

I think this should only be called when xlog_recover_finish didn't
return an error.
