008847f66c3 ("workqueue: allow rescuer thread to do more work.") made
the rescuer worker requeue the pwq immediately if there may be more
work items which need rescuing instead of waiting for the next mayday
timer expiration. Unfortunately, it checks only whether the pool needs
help from rescuers,
Simple cleanups found when I was reviewing the lkml patches.

Thus, when kobject_init_and_add() returns an error,

Hi,
I wonder if we can "generalize" this a bit and use SW sequencer to run
commands HW sequencer does not support? The BIOS can then setup the
allowed SW sequencer opcodes and lock the thing down if needed.
There are couple of other commands related to FSR register where this
could be useful.
