Considering that glibc has seen the light ¹ now too, can we please
do something about these now? The BSD tools (not just NetBSD ®) have
been using this for far longer after all…
Currently (git pull --ff torvalds master), we have:
• 2 occurrences of files *inside* the Linux kernel defining __unused
to ² __attribute__((unused)) themselves
• 68 struct members and function arguments called __unused

I think __unused0 is okay as it matches current __unused[0-9] in
use by other parts of the Linux kernel – although glibc now uses
__glibc_reserved[0-9], I think this doesn't look like the Linux
kernel should use it ☻☺

â‘¡ I've recently come to the belief that this should be
__attribute__((__unused__)) in all cases, i.e. all those
attribute namings need double underscores before and after,
as some software likes to #define printf to something else,
lighttpd does #define bounded something else, so there's
probably software out there containing #define unused foo.
