Hi James, trying to figure this annoying lpfc_set_rrq_active() bug I've found the nodelist pointer handling in the lpfc io buffers a bit strange; there's a 'ndlp' pointer, but for scsi the nodelist is primarily accessed via the 'rdata' pointer (although not everywhere). For NVMe it's primarily the 'ndlp' pointer, apparently, but the usage is quite confusing. So here's a patchset to straighten things up; it primarily moves the anonymous protocol-specific structure in the io buffer to a named one, and always accesses the nodelist through the protocol-specific rport data structure.
It also has the nice side-effect that the protocol-specific areas are aligned now, so clearing the 'rdata' pointer on the scsi side will be equivalent to clearing the 'rport' pointer on the nvme side. And it reduces the size of the io buffer. Let me know what you think.
