Subject: blkdebug: Don't confuse image as backing file
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6b826af7b010ed1963b1e7bfb5c389dcdbaff222;p=osstest%2Fqemu.git

blkdebug: Don't confuse image as backing file

The word "backing file" nowadays refers to the backing_hd in the
external snapshot sense (i.e. bs->backing_hd), instead of the file sense
(bs->file). Correct the comment to use the right term.
