Fedora has temporarily disabled lock elision on F20, F21, rawhide. They've detected the need to keep it enabled on s390, s390x though. https://bugzilla.redhat.com/show_bug.cgi?id=1146967 Apparently there's at least one codepath that attempts to use lock elision regardless of --enable-lock-elision in x86 in rwlock. I'm searching for it. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
