What might look unnecessary at first glance is a bit more nuanced than we'd both like... I'm concerned about switching to using the global system_wq and calling flush_scheduled_work() when resuming a DM table (calls a DM target's ->dtr() via dm_table_destroy in drivers/md/dm-ioctl.c:do_resume). This introduces potential for a DM table swap performing a storm of additional unrelated works. Definitely needs further review.
