From c8753d55afb436fd6a25c8bbe8d783f6dcf1c9f8 Mon Sep 17 00:00:00 2001 From: Vijay Subramanian Date: Thu, 2 Oct 2014 10:00:43 -0700 Subject: [PATCH] net: Cleanup skb cloning by adding SKB_FCLONE_FREE SKB_FCLONE_UNAVAILABLE has overloaded meaning depending on type of skb. 1: If skb is allocated from head_cache, it indicates fclone is not available. 2: If skb is a companion fclone skb (allocated from fclone_cache), it indicates it is available to be used. To avoid confusion for case 2 above, this patch replaces SKB_FCLONE_UNAVAILABLE with SKB_FCLONE_FREE where appropriate. For fclone companion skbs, this indicates it is free for use. SKB_FCLONE_UNAVAILABLE will now simply indicate skb is from head_cache and cannot / will not have a companion fclone. Signed-off-by: Vijay Subramanian Signed-off-by: David S.
