+Subject: blktrace: use inline function for blk_trace_remove() while blktrace is disabled
+
+From: Yu Kuai <yukuai3@huawei.com>
+
+commit cbe7cff4a76bc749dd70264ca5cf924e2adf9296 upstream.
+
+If config is disabled, call blk_trace_remove() directly will trigger
+build warning, hence use inline function instead, prepare to fix
+blktrace debugfs entries leakage.
