From 06489b4eec832227b6f30b4b43ab26a2c50d9225 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 18 Oct 2007 03:05:28 -0700 Subject: sysctl: remove broken cdrom binary sysctls The binary interface for the cdrom sysctls can't possilby work. So remove the binary sysctls and update the test for finding out which sysctl table entry we are dealy with to use the procname and not the ctl_name (which I am removing). Signed-off-by: Eric W.
