Hi,
This is a small patch series which fixes the IO size calulation in the
nvme_probe.
The first patch replaces the ctrl->page_size with a macro. The second
patch calculates the maximum value based on NVMe PRP and SGL size.
I've tested this patch with different block sizes 4k-128k on NVMe QEMU
and NVMe PCIe (non-SGL) controller.
Regards,
Chaitanya
* Changes from V1:-
-------------------
1. Remove the ctrl->page_size and use macro instead.
2. Get rid of the conditional operater and use max_t() for SGL vs PRP
size calulation.

nvme-core: replace ctrl page size with a macro
nvme-pci: use max of PRP or SGL for iod size
