From 6a5ac9846508ad7d1d23881d9d5add35f2e6ae71 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 15 Jun 2018 14:55:21 -0700 Subject: block: Make struct request_queue smaller for CONFIG_BLK_DEV_ZONED=n Exclude zoned block device members from struct request_queue for CONFIG_BLK_DEV_ZONED == n. Avoid breaking the build by only building the code that uses these struct request_queue members if CONFIG_BLK_DEV_ZONED != n.
