Subject: qa: krbd_blkroset.t: eliminate a race in the open_count test
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=006e47e9ca691deb377fb76f7a23b6feec874865;p=ceph.git

qa: krbd_blkroset.t: eliminate a race in the open_count test

Even at QD=1, dd may take less than 10 seconds to work its way to the
end of a 10M image, producing "No space left on device" error instead
of the expected "Operation not permitted" error which is supposed to
arise from the device getting marked read-only while opened.
