Ugh.  So all that slowdown comes from one thing - not taking the parent's lock in
lock_for_kill() (and not dropping the parent's lock in __dentry_kill(), since the
caller is not holding it now).  Other changes in there undo some of that slowdown,
but not enough to balance it.

Note that it's not reordering the removal from list of children vs. ->d_iput(),
not postponing the decrement of parent's refcount, etc. - it's literally not bothering
with holding parent->d_lock over the beginning of already reordered __dentry_kill().
And no, there's no cond_resched() anywhere in the affected areas.

What the hell is going on?  Was ->d_lock on parent serving as a throttle and reducing
the access rate to something badly contended down the road?  I don't see anything
of that sort in the profile changes, though...

Any ideas would be very welcome - I'm really at loss here.  Help?
