Subject: block: don't reject too large max_user_sectors in blk_validate_limits
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=038105a200689ae07eb9e804ca2295e628a45820;p=linux.git

block: don't reject too large max_user_sectors in blk_validate_limits

We already cap down the actual max_sectors to the max of the hardware
and user limit, so don't reject the configuration.
