[PATCH 0/2] block: fix hang in elevator_change() and improve elevator_set_none

[Ming Lei <ming.lei@redhat.com>]

Hello Jens,

The 1st patch fixes one hang in elevator_change(), which is introduced in
elevator unifying patchset.

The 2nd patch tries to avoid to freeze & drain IO in elevator_set_none().

Thanks,


Ming Lei (2):
  block: move queue quiesce into elevator_change()
  block: avoid unnecessary queue freeze in elevator_set_none()
