On Linux, the minimum required kernel version for Go 1.18 was be changed to 2.6.32, see #45964. The pipe2 syscall was added in 2.6.27. All other platforms already provide the pipe2 syscall in the minimum supported version: - DragonFly BSD added it in version 4.2, see https://www.dragonflybsd.org/release42/ - FreeBSD added it in version 10.0, see https://www.freebsd.org/cgi/man.cgi?pipe(2)#end - NetBSD added it in version 6.0, see https://man.netbsd.org/pipe2.2#HISTORY - OpenBSD added it in version 5.7, see https://man.openbsd.org/pipe.2#HISTORY - Illumos supports it since 2013, see https://www.illumos.org/issues/3714 - Solaris supports it since 11.4 This also allows to remove setNonblock which was only used in the pipe fallback path on these platforms.
