From 9f5c6dbe907fe6227006ab51179eaa50a63559cb Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Tue, 5 Dec 2023 13:20:09 -0500 Subject: [PATCH 092/101] scsi: remove outdated AioContext lock comment RH-Author: Kevin Wolf RH-MergeRequest: 214: Remove AioContext lock RH-Jira: RHEL-15965 RH-Acked-by: Miroslav Rezanina RH-Acked-by: Stefan Hajnoczi RH-Commit: [23/26] 96e2e7d2e6a160ce4d695060f902d21030b3b1d8 (kmwolf/centos-qemu-kvm) The SCSI subsystem no longer uses the AioContext lock. Request processing runs exclusively in the BlockBackend's AioContext since "scsi: only access SCSIDevice->requests from one thread" and hence the lock is unnecessary.
