Re: [PATCH 01/11] selftests: ublk: make ublk_stop_io_daemon() more reliable

Improve ublk_stop_io_daemon() in the following ways:

• don't wait if ->ublksrv_pid becomes -1, which means that the disk

has been stopped

• don't wait if ublk char device doesn't exist any more, so we can

avoid to rely on inoitfy for wait until the char device is closed

And this way may reduce time of delete command a lot.

Looks good,
