Recent events have prompted a Linux position statement on inclusive
terminology. For symbol names, avoid introducing new usage of the words
'slave' and 'blacklist'. Recommended replacements for 'slave' are:
'secondary', 'subordinate', 'replica', 'responder', 'follower', 'proxy',
or 'performer'.  Recommended replacements for blacklist are: 'blocklist'
or 'denylist'.
