Subject: Update / fix extroot comments
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=128ecaf8da9887b3a1fe35ed95d352a9b64b6342;p=project%2Ffstools.git

Update / fix extroot comments

Comment in start() was invalid as mount_extroot() doesn't handle any
mounting internally. It was a misunderstanding coming from block.c
function called just the same.
