From 63a1c95f3fe48b4e9fe0c261b376e5e527b71b25 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 25 Apr 2019 12:32:04 -0700 Subject: [PATCH] net/tls: byte swap device req TCP seq no upon setting To avoid a sparse warning byteswap the be32 sequence number before it's stored in the atomic value. While at it drop unnecessary brackets and use kernel's u64 type. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S.
