bdi: remove bdi->wb_lock locking around bdi->dev clearing in bdi_unregister()
The only places where NULL test on bdi->dev is used are bdi_[un]register(). The functions can't be called in parallel anyway and there's no point in protecting bdi->dev clearing with a lock. Remove bdi->wb_lock grabbing around bdi->dev clearing and move it after device_unregister() call so that bdi->dev doesn't have to be cached in a local variable. This patch shouldn't introduce any behavior difference. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@fb.com>
