Subject: [PATCH v2 0/2] scsi-disk: Add FUA write support
Date: Fri, 11 Apr 2025 12:30:34 +0100 [thread overview]
Message-ID: <20250411113036.786841-1-afaria@redhat.com> (raw)
Add scsi-disk support for Force Unit Access (FUA) writes. The first patch lets
us avoid FUA emulation when the underlying driver supports it natively. The
second patch makes scsi-disk devices advertise FUA support by default.
v2:
- Drop FUA write emulation logic since the block layer already does that.
- Add machine type compat for "dpofua".
