    [PATCH] sysctl: remove insert_at_head from register_sysctl · 0b4d4147
    Eric W. Biederman authored
    The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name.  Which is
    pain for caching and the proc interface never implemented.
    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.
    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.
