From 723464ec5522b479bceaa253994d4b865300bd95 Mon Sep 17 00:00:00 2001 From: Nicolas Lacasse Date: Tue, 3 Nov 2020 12:10:01 -0800 Subject: Make pipe min/max sizes match linux. The default pipe size already matched linux, and is unchanged. Furthermore `atomicIOBytes` is made a proper constant (as it is in Linux). We were plumbing usermem.PageSize everywhere, so this is no functional change.
