Subject: [PATCH v2 0/3] xen-blk{front,back}: Fix the broken semantic and flow of feature-persistent
Date: Wed, 31 Aug 2022 16:58:21 +0000 [thread overview]
Message-ID: <20220831165824.94815-1-sj@kernel.org> (raw)
Changes from v1
(https://lore.kernel.org/xen-devel/20220825161511.94922-1-sj@kernel.org/)
- Fix the wrong feature_persistent caching position of blkfront
- Set blkfront's feature_persistent field setting with simple '&&'
instead of 'if' (Pratyush Yadav)
This patchset fixes misuse of the 'feature-persistent' advertisement
semantic (patches 1 and 2), and the wrong timing of the
'feature_persistent' value caching, which made persistent grants feature
always disabled.

xen-blkback: Advertise feature-persistent as user requested
xen-blkfront: Advertise feature-persistent as user requested
xen-blkfront: Cache feature_persistent value before advertisement
