From f575e0495b7f1f0305dc6fa48d4a96b9f4cc906e 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.
