Subject: [PULL 2/5] scsi-disk: Advertise FUA support by default
Date: Thu, 22 May 2025 20:31:12 +0200	[thread overview]
Message-ID: <20250522183115.246746-3-kwolf@redhat.com> (raw)
In-Reply-To: <20250522183115.246746-1-kwolf@redhat.com>

From: Alberto Faria <afaria@redhat.com>

Allow the guest to submit FUA requests directly, instead of forcing it
to emulate them using a regular flush.
