Subject: [PATCH] sysctl: remove support for CTL_ANY
X-Git-Tag: v2.6.21-rc1~195
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6703ddfcce61ad66db606085a8d42dcab264f840;p=linux-2.6

[PATCH] sysctl: remove support for CTL_ANY

There are currently no users in the kernel for CTL_ANY and it only has effect
on the binary interface which is practically unused.

So this complicates sysctl lookups for no good reason so just remove it.
