Subject: blktrace: accept -v (lower case) for version info as well
X-Git-Tag: blktrace-1.0.0~13
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=5d4f19d9812264bfb45427716330d0bd2529dfd9;p=blktrace.git

blktrace: accept -v (lower case) for version info as well

Christof Schmitt <christof.schmitt@de.ibm.com> points out that the
documentation uses -v but blktrace supports only -V, so change
blktrace to accept both cases.
