From e142723700baaa621c1b4649ec17a714a4d4a582 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 1 Apr 2019 22:59:09 +0200 Subject: macsec: add noinline tag to avoid a frame size warning seen with debug config: drivers/net/macsec.c: In function 'dump_secy': drivers/net/macsec.c:2597: warning: the frame size of 2216 bytes is larger than 2048 bytes [-Wframe-larger-than=] just mark it with noinline_for_stack, this is netlink dump code. v2: use 'static noinline_for_stack int' consistently Cc: Sabrina Dubroca Signed-off-by: Florian Westphal Reviewed-by: Sabrina Dubroca Signed-off-by: David S.
