bfq: Fix bfq linkage error
Since commit 795fe54c2a828099e ("bfq: Add per-device weight"), bfq uses blkg_conf_prep() and blkg_conf_finish(), which are not exported. So, it causes linkage error if bfq compiled as a module. Fixes: 795fe54c2a828099e ("bfq: Add per-device weight") Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
