Subject: buffer: Convert __bh_read_batch to bh_submit()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=44d325ebba175e73711a4bd90f30e1bc192242d9;p=thirdparty%2Flinux.git

buffer: Convert __bh_read_batch to bh_submit()

Avoid an extra indirect function call and changing the buffer refcount
by using bh_submit() instead of submit_bh().
