[PATCH v6 0/2] cancel all throttled bios in del_gendisk()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If del_gendisk() is done when some io are still throttled, such io
will not be handled until the throttle is done, which is not
necessary.

Changes in v2:
 - move WARN_ON_ONCE() from throtl_rb_first() to it's caller
 - merge some patches into one.

Changes in v3:
 - some code optimization in patch 1
 - hold queue lock to cancel bios in patch 2

Changes in v4:
 - delete rcu_read_lock() and rcu_read_unlock() in patch 2

Changes in v5:
 - add comment about rcu lock

Changes in v6:
 - revert to include rcu lock with some comments.
