[Qemu-devel] [PATCH v5 18/22] blkverify: Don't require protocol filename

[Max Reitz]

If the filename is not prefixed by "blkverify:" in
blkverify_parse_filename(), the blkverify driver was not selected
through that protocol prefix, but by an explicit command line (or QMP)
option (like driver=blkverify). Contrary to the current reaction, this
is no longer a problem; both images may be specified through the "test"
and "raw" options, respectively.

If a filename has been given, pass it as the test image filename.
