From c84f3a4004076b0e3dcef0a17573d85eb90ef5fc Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 8 Sep 2021 10:41:56 +0200 Subject: [PATCH] syscall: drop fallback to pipe in Pipe on linux/arm Follow-up for CL 346789 The minimum required Linux kernel version for Go 1.18 will be changed to 2.6.32, see #45964. The pipe2 syscall was added in 2.6.27, so the fallback to use pipe in Pipe on linux/arm can be removed.
