From 0a7ae4be8d1dedda901dc0e38ea5a0cfd7763126 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Thu, 2 Sep 2021 13:19:27 +0200 Subject: [PATCH] unix: drop fallback to pipe in Pipe on linux/arm Same as CL 347349 does for package syscall. The minimum required Linux kernel version for Go 1.18 will be changed to 2.6.32, see golang/go#45964. The pipe2 syscall was added in 2.6.27, so the fallback to use the pipe syscall in syscall.Pipe on linux/arm can be removed.
