Subject: [PATCH v2] seg6_iptunnel: Refactor seg6_lwt_headroom out of uapi header
Date: Fri, 31 Jul 2020 07:40:32 +0000 [thread overview]
Message-ID: <20200731074032.293456-1-ioanaruxandra.stancioi@gmail.com> (raw)
From: Ioana-Ruxandra Stăncioi <stancioi@google.com>
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 <davem@davemloft.net>
Signed-off-by: Ioana-Ruxandra Stăncioi <stancioi@google.com>
---
v2:
* Apply David's suggestion and just move the function.
