Bellinger; Or Gerlitz; Jenny Derzhavetz; Steve Wise > Subject: [PATCH v1 00/10] iSER support for remote invalidate > > This patchset adds remote invalidation support to iser initiator and > target. The support negotiation for this feature is based on IBTA > annex 12 "Support for iSCSI Extensions for RDMA" carried in rdma_cm > private data. > > Remote invalidation allows a peer host to invalidate a remote key > as part of a SEND operation. This feature allows a host to avoid > invalidating an rkey locally. By supporting this feature iser initiator > can save extra latency and processing time yielded by invalidating > the memory key locally. > > The initiator feature support is dependent on: > - fastreg is used (not FMR) > - always_register=Y > > In this case the initiator will expose support for remote invalidation, > however it will not blindly rely on the target to do so and will verify > that in the work completion information. The iser target now looks into > the iser header in the CM request and in case the initiator supports > remote invalidation it will respond it will use remote invalidation for > provided remote keys. > Series looks ok to me.
