[PATCH] sysctl: update comments to new registration APIs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The sysctl registration APIs do not need a terminating table entry
anymore and with commit acc154691fc7 ("sysctl: Warn on an empty procname element")
even emit warnings if such a sentinel entry is supplied.

While at it also remove the mention of "table->de" which was removed in
commit 3fbfa98112fc ("[PATCH] sysctl: remove the proc_dir_entry member for the sysctl tables")
back in 2007.
