Subject: block: remove the nr_sectors variable in generic_make_request_checks
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e439ab710fb0564dccb52b0519b3d354ea2a9c50;p=linux.git

block: remove the nr_sectors variable in generic_make_request_checks

The variable is only used once, so just open code the bio_sector()
there.
