Subject: block/013: Fix check for blockdev output
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e86852d221f38536fbb1ee595f2276d8a13d4be3;p=users%2Fsagi%2Fblktests.git

block/013: Fix check for blockdev output

In some systems the operator "<<<" may not behave as expected. Replace
this operator by a more canonical approach to grep content from a
variable.
