Subject: Fix devname which was faked by always using "(unavailable)".
X-Git-Tag: pre-name-change~450
X-Git-Url: http://www.aleph1.co.uk/gitweb/?p=yaffs2.git;a=commitdiff_plain;h=58f638975518ac0b6638bf5037bda4a2b56e78af

Fix devname which was faked by always using "(unavailable)".

Make proper use of bdevname() and sb->s_bdev,
but maybe it is better to simply use sb->s_id?
