From 8113c095672f6504b23eba6edf4a57b5f7f744af Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Fri, 4 Aug 2017 21:31:43 -0700 Subject: net_sched: use void pointer for filter handle Now we use 'unsigned long fh' as a pointer in every place, it is safe to convert it to a void pointer now. This gets rid of many casts to pointer. Cc: Jamal Hadi Salim Cc: Jiri Pirko Signed-off-by: Cong Wang Acked-by: Jamal Hadi Salim Signed-off-by: David S.
