From d8a2c89c8636405ad0b234f111d22c00c37e452b Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 24 Mar 2015 16:15:17 +0300 Subject: rbd: mark block queue as non-rotational Set QUEUE_FLAG_NONROT. Following commit b277da0a8a59 ("block: disable entropy contributions for nonrot devices") we should also clear QUEUE_FLAG_ADD_RANDOM, but it's off by default for blk-mq drivers, so just note it in the comment. Also remove physical block size assignment - no sense in repeating defaults that are not going to change.
