Subject: imsm: fix: correct debug printing of the volume's name
X-Git-Tag: mdadm-3.2.3~126
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c4acd1e5c83a7ad746e8d0a0949e097c8aaf525c;p=thirdparty%2Fmdadm.git

imsm: fix: correct debug printing of the volume's name

The volume's name is saved in the array of chars.
All elements of the array can have nonzero values
and the next byte in memory does not have to have
the value of 0, so one must be cautious when
printing out the volume's name.
