Subject: nilfs2: Convert nilfs_mdt_submit_block to bh_submit()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9fa6916b1141e3648779e99039b02d4c57225f6;p=thirdparty%2Fkernel%2Flinux.git

nilfs2: Convert nilfs_mdt_submit_block to bh_submit()

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