Wow, that's incredibly impressive! :-)

Yeah, we got a similar speedup on -rt by pushing those super-block files
list into per-cpu lists and doing crazy locking on them.

Of course avoiding them all together, like done here is a nicer option
but is sadly not a possibility for regular files (until hch gets around
to removing the need for the list).

We should have finished this long ago, thanks for the reminder.
