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?
Thanks,
Bart. |
