[PATCH v2 0/4] clarify NVMe status symbol names

[Weiwen Hu <huweiwen@linux.alibaba.com>]

This patchset clarifies the NVMe status related symbol names.
- status: the u16 field in the struct nvme_request.
- SC:     status code,      status & 0x00FF
- SCT:    status code type, status & 0x0700
This should match the NVMe spec and most of the existing code.
The exceptions are unified in this patchset.

It may be a little bit strange that we should use NVME_SCT_SC_MASK when
matching the NVME_SC_* codes. But changing all the codes to NVME_SCT_SC_*
requires too much changes, and making the names too long.
So I choose to keep them.

The previous version is:
https://lore.kernel.org/linux-nvme/20240529122300.92377-1-huweiwen@linux.alibaba.com/T

Changes in v2:
- Add a mailmap entry for myself.
- Rebased on nvme-6.10, dropped the patch that is already applied.
- The parameter of nvme_status_to_pr_err is renamed to "status", to make it
  shorter and matching the existing code.

Weiwen Hu (4):
  nvme: rename nvme_sc_to_pr_err to nvme_status_to_pr_err
  nvme: fix status magic numbers
  nvme: rename CDR/MORE/DNR to NVME_STATUS_*
  mailmap: add entry for Weiwen Hu
