You should probably just send the patchset to the list (and cc Jens on
the block changes).

Patch 1 looks good as is.  But Jens suggested that Patch 2 should hook
off the on stack plugging rather than adding yet another hook to
kernel/sched/core.c

And I agree with Joe, we want this DM-only limit to be opt-in per-target
(so disabled by default).
