+AD4 The default behavior of the SCSI core is to set the block layer request

+AD4 sizes, increase max+AF8-segment+AF8-size for the SRP initiator.

+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.
