From 88fab21c691bb1ff164e540735237a385e3afeaf Mon Sep 17 00:00:00 2001 From: Ioana-Ruxandra Stăncioi Date: Mon, 3 Aug 2020 07:33:33 +0000 Subject: seg6_iptunnel: Refactor seg6_lwt_headroom out of uapi header MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Refactor the function seg6_lwt_headroom out of the seg6_iptunnel.h uapi header, because it is only used in seg6_iptunnel.c. Moreover, it is only used in the kernel code, as indicated by the "#ifdef __KERNEL__". Suggested-by: David Miller Signed-off-by: Ioana-Ruxandra Stăncioi Signed-off-by: David S.
