Subject: [PATCH 0/2] scsi-disk: Add FUA write support
Date: Tue, 4 Mar 2025 15:52:30 +0000 [thread overview]
Message-ID: <20250304155232.1325581-1-afaria@redhat.com> (raw)
Add support for Force Unit Access (FUA) writes. The first patch makes scsi-disk
devices advertise FUA support by default; FUA requests will be emulated through
a regular write followed by a flush. The second patch lets us avoid FUA
emulation when the underlying block driver supports it natively.
Alberto Faria (2):
scsi-disk: Advertise FUA support by default
scsi-disk: Add native FUA support
