Date: Thu, 14 Mar 2019 15:15:14 +0900 From: Sergey Senozhatsky <sergey.senozhatsky.work@...il.com> To: Eric Dumazet <edumazet@...gle.com> Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Sergey Senozhatsky <sergey.senozhatsky@...il.com> Subject: [PATCH] tcp: don't use __constant_cpu_to_be32 A trivial patch. cpu_to_be32() is capable enough to detect __builtin_constant_p() and to use an appropriate compile time ___constant_swahb32() function. So we can use cpu_to_be32() instead of __constant_cpu_to_be32().
