[Ksummit-discuss] [PATCH v2] CodingStyle: Inclusive Terminology

[Dan Williams <dan.j.williams@intel.com>]

Linux maintains a coding-style and its own idiomatic set of terminology.
Update the style guidelines to recommend replacements for the terms
master/slave and blacklist/whitelist.

Changes since v1 [1]
- Drop inclusive-terminology.rst, it is in the lore archives if the
  arguments are needed for future debates, but otherwise no pressing
  need to carry it in the tree (Linus, James)

- Update the recommended terms to include replacement for 'master' and
  'whitelist' (Kees, Andy)

- Add 'target' as a replacement (Andy)

- Add 'device' as a replacement (Mark)

- Collect acks and signed-off-bys. Yes, the sign-offs are not reflective
  of a submission chain, but I kept "Signed-off-by" if people offered
  it.

- Non-change: I did not add explicit language as to what to do with
  existing usages. My personal inclination is to prioritize this
  coding-style cleanup higher than others, but the coding-style document
  has typically not indicated policy on how cleanups are handled by
  subsystems. It will be a case by case effort and consideration.

 See chapter 6 (Functions).
 
+For symbol names, avoid introducing new usage of 'master/slave' (or
+'slave' independent of 'master') and 'blacklist/whitelist'. Recommended
+replacements for 'master/slave' are: 'main/{secondary,subordinate}',
+'primary/replica', '{initiator,requester}/{target,responder}',
+'host/{device,proxy}', or 'leader/{performer,follower}'. Recommended
+replacements for 'blacklist/whitelist' are: 'denylist/allowlist' or
+'blocklist/passlist'.
+
+Exceptions for introducing new usage is to maintain a userspace ABI/API,
+or when updating code for an existing (as of 2020) hardware or protocol
+specification that mandates those terms. For new specifications
+translate specification usage of the terminology to the kernel coding
+standard where possible.
