The patch titled
sysctl: remove broken cdrom binary sysctls
has been removed from the -mm tree. Its filename was
sysctl-remove-broken-cdrom-binary-sysctls.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: sysctl: remove broken cdrom binary sysctls
From: Eric W. Biederman <[EMAIL PROTECTED]>
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).
