Introduction of 'feature_persistent' made two bugs. First one is wrong overwrite of 'vbd->feature_gnt_persistent' in 'blkback' due to wrong parameter value caching position, and the second one is unintended behavioral change that could break previous dynamic frontend/backend persistent feature support changes. This patchset fixes the issues.Changes from v3 (https://lore.kernel.org/xen-devel/20220715175521.126649-1...@kernel.org/) - Split 'blkback' patch for each of the two issues - Add 'Reported-by: Andrii Chepurnyi <andrii.chepurny...@gmail.com>' Changes from v2 (https://lore.kernel.org/xen-devel/20220714224410.51147-1...@kernel.org/) - Keep the behavioral change of v1 - Update blkfront's counterpart to follow the changed behavior - Update documents for the changed behavior Changes from v1 (https://lore.kernel.org/xen-devel/20220106091013.126076-1-mhe...@amazon.de/) - Avoid the behavioral change (https://lore.kernel.org/xen-devel/20220121102309.27802-1...@kernel.org/) - Rebase on latest xen/tip/linux-next - Re-work by SeongJae Park <s...@kernel.org> - Cc stable@ Maximilian Heyne (1): xen-blkback: Apply 'feature_persistent' parameter when connect SeongJae Park (2): xen-blkback: fix persistent grants negotiation xen-blkfront: Apply 'feature_persistent' parameter when connect .../ABI/testing/sysfs-driver-xen-blkback | 2 +- .../ABI/testing/sysfs-driver-xen-blkfront | 2 +- drivers/block/xen-blkback/xenbus.c | 20 ++++++++----------- drivers/block/xen-blkfront.c | 4 +--- 4 files changed, 11 insertions(+), 17 deletions(-)
