The patch titled
sysctl: update sysctl_check_table
has been removed from the -mm tree. Its filename was
sysctl-update-sysctl_check_table.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: sysctl: update sysctl_check_table
From: Eric W. Biederman <[EMAIL PROTECTED]>
Well it turns out after I dug into the problems a little more I was returning
a few false positives so this patch updates my logic to remove them.
- Don't complain about 0 ctl_names in sysctl_check_binary_path
It is valid for someone to remove the sysctl binary interface
and still keep the same sysctl proc interface.
- Count ctl_names and procnames as matching if they both don't
exist.
- Only warn about missing min&max when the generic functions care.
