[PATCH v3 0/2] scsi-disk: Add FUA write support

Posted by Alberto Faria 6 months, 2 weeks ago

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.

v3:
- Restore flush on VERIFY.
- Modify hw_compat_10_0 instead of hw_compat_9_2.

v2:
- Drop FUA write emulation logic since the block layer already does that.
- Add machine type compat for "dpofua".

Thanks, applied to the block branch.
