File 0169-scsi-disk-fix-rerror-werror-ignore.patch of Package qemu.20395
From: Paolo Bonzini <pbonzini@redhat.com>
Date: Sat, 13 Oct 2018 11:52:34 +0200
Subject: scsi-disk: fix rerror/werror=ignore
rerror=ignore was returning true from scsi_handle_rw_error but the callers were not
calling scsi_req_complete when rerror=ignore returns true (this is the correct thing
to do when true is returned after executing a passthrough command). Fix this by
calling it in scsi_handle_rw_error.
