[PATCH 06/23] sysctl: Remove references to ctl_name and strategy from the generic sysctl table

Eric W. Biederman
2009-11-08T12:26:47Z

From: Eric W. Biederman <ebiederm@xmission.com>

Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name
and .strategy members of sysctl tables are dead code. Remove them.
