-From 5de7c318804a7b1edce8562d4891b4c74aac0677 Mon Sep 17 00:00:00 2001
-From: Michael Jeanson <mjeanson@efficios.com>
-Date: Wed, 20 Mar 2019 11:07:35 -0400
-Subject: [PATCH] compat: work around broken _SC_NPROCESSORS_CONF on MUSL libc
-
-On MUSL libc the _SC_NPROCESSORS_CONF sysconf will report the number of
-CPUs allocated to the task based on the affinity mask instead of the
-total number of CPUs configured on the system.
-
-Upstream-Status: Accepted [1] [5de7c318804a7b1edce8562d4891b4c74aac0677]
