From d6296d39e90c9075bc2fc15f1e86dac44930d4b5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 1 May 2017 10:19:08 -0600 Subject: blk-mq: update ->init_request and ->exit_request prototypes Remove the request_idx parameter, which can't be used safely now that we support I/O schedulers with blk-mq. Except for a superflous check in mtip32xx it was unused anyway. Also pass the tag_set instead of just the driver data - this allows drivers to avoid some code duplication in a follow on cleanup.
