Linux-2.6.33 compat, .ctl_name removed from struct ctl_table

Browse Source 
As of linux-2.6.33 the ctl_name member of the ctl_table struct
has been entirely removed.  The upstream code has been updated
to depend entirely on the the procname member.  To handle this
all references to ctl_name are wrapped in a CTL_NAME macro which
simply expands to nothing for newer kernels.  Older kernels are
supported by having it expand to .ctl_name = X just as before.
