That means that elements of +AD4 scatterlists are limited to 64 KB. Since RDMA adapters support larger +AD4 sizes, increase max+AF8-segment+AF8-size for the SRP initiator. +AD4 +AD4 Notes: +AD4 - The SCSI max+AF8-segment+AF8-size parameter was introduced in kernel v5.0. See +AD4 also commit 50c2e9107f17 (+ACI-scsi: introduce a max+AF8-segment+AF8-size +AD4 host+AF8-template parameters+ACI). +AD4 - Some other block drivers already set max+AF8-segment+AF8-size to UINT+AF8-MAX, +AD4 e.g. nbd and rbd. Hi Jason and Doug, Can one of you have a look at this patch? Thanks, Bart.
