Many subsystems use system_freezable_wq and/or
system_freezable_power_efficient_wq to queue work that should not run while
processes are frozen. Should it be mentioned in the patch description that
this patch does not affect workqueues for which WQ_FREEZABLE has been set?

What about the many drivers outside filesystems that use the set_freezable() /
try_to_freeze() / wait_event_freezable() API?
