[PATCH v3 0/2] Fix persistent grants negotiation with a behavior change
From: SeongJae Park
Date: Fri Jul 15 2022 - 13:56:01 EST
The first patch of this patchset fixes 'feature_persistent' parameter
handling in 'blkback' to respect the frontend's persistent grants
support always. The fix makes a behavioral change, so the second patch
makes the counterpart of 'blkfront' to consistently follow the behavior
change.
