From 8e42d239cb027143915cae13eb2ecf1360ee24de Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Tue, 7 Jan 2020 13:58:17 -0800 Subject: block: mark zone-mgmt bios with REQ_SYNC In the current implementation, final zone-mgmt request is issued with submit_bio_wait() which marks the bio REQ_SYNC. This is needed since immediate action is expected for zone-mgmt requests as these are blocking operations. This also bypasses the scheduler in the blk_mq_make_request() and dispatches the request directly into the hw ctx. This patch marks all the chained bios REQ_SYNC so that we can have above-mentioned behavior for non-final bios also.
