From 06b16a0bab0098e44c4cdffef2e92ed1e5a0abcc Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Fri, 2 Mar 2018 17:36:25 -0500 Subject: [PATCH] Fix: reset cached vpid context on fork We currently reset the cached vtid on fork but not the vpid. This is not a problem on Linux because we don't cache the vpid internally but call getpid() directly and rely on the glibc pid cache.
