Ah, good that you pinged me because I have the series ready but I was
waiting for your answers to some explanations... In particular discussion
around patch 3 (move iput() outside of transaction), patch 15 (dropping of
j_state_lock around t_tid load), patch 18 (possible large overreservation
of descriptor blocks due to rounding), and 21 (change of on-disk format for
revoke descriptors).

Out of these I probably find the overreservation due to rounding the most
serious and easy enough to handle so I'll fix that and then resend the
series unless you raise your objection also in some other case.
