From 0bf6cd5b9531bcc29c0a5e504b6ce2984c6fd8d8 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 27 Sep 2015 21:01:51 +0200 Subject: blk-mq: factor out a helper to iterate all tags for a request_queue And replace the blk_mq_tag_busy_iter with it - the driver use has been replaced with a new helper a while ago, and internal to the block we only need the new version.
