[Dan Williams]

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 v2 [1]:
- Pick up missed sign-offs and acks from Jon, Shuah, and Christian
  (sorry about missing those earlier).

- Reformat the replacement list to make it easier to read.

- Add 'controller' as a suggested replacement (Kees and Mark)

- Fix up the paired term for 'performer' to be 'director' (Kees)

- Collect some new acks, reviewed-by's, and sign-offs for v2.

- Fix up Chris's email

 See chapter 6 (Functions).
 
+For symbol names and documentation, avoid introducing new usage of
+'master / slave' (or 'slave' independent of 'master') and 'blacklist /
+whitelist'.
+
+Recommended replacements for 'master / slave' are:
+    '{primary,main} / {secondary,replica,subordinate}'
+    '{initiator,requester} / {target,responder}'
+    '{controller,host} / {device,worker,proxy}'
+    'leader / follower'
+    'director / performer'
+
+Recommended replacements for 'blacklist/whitelist' are:
+    'denylist / allowlist'
+    '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.
