[PATCH 0/4] scsi_debug: improve failure rates

[Luis Chamberlain]

When using scsi_debug to create virtual devices we can often run into
failures which are really just false positives, and the failure was the
inability to remove the module. Addressing this is not easy. While we
can learn from what blktests folks do and use udevadm settle, that's
not sufficient by any means. This addresses the other pieces needed.

More work is also needed on the scsi_debug driver front.

Makes me wonder if a patient kmod removal option is then desirable
upstream on kmod (just the one which waits to refcnt 0), given this sort
of test case. Lucas?

Luis Chamberlain (4):
  common/config: disable udevadm settle if CONFIG_NET is disabled
  common/scsi_debug: use udevadm settle instead of sleeping
  common/module: add a patient module rmmod
  common/scsi_debug: use the patient module remover
