Subject: block/032: add test to cover umount one deleted disk
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f28eb905207a2008c295360ea886bc4b75124251;p=users%2Fsagi%2Fblktests.git

block/032: add test to cover umount one deleted disk

disk can be disappear any time because of error handling, when
it is usually being mounted. Make sure umount can be done successfully
after disk deleting is done from error handling.
