Subject: nilfs2: Convert nilfs_gccache_submit_read_data to bh_submit()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=143a7cea4280562a0cdc3ca43e6e1ced4f8ec61d;p=thirdparty%2Fkernel%2Flinux.git

nilfs2: Convert nilfs_gccache_submit_read_data to bh_submit()

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