From 5dd01be14565df814408327971775f36e55bf5e3 Mon Sep 17 00:00:00 2001 From: Andrea Arcangeli Date: Tue, 22 Sep 2015 14:59:06 -0700 Subject: [PATCH] userfaultfd: selftest: don't error out if pthread_mutex_t isn't identical On ppc big endian this check fails, the mutex doesn't necessarily need to be identical for all pages after pthread_mutex_lock/unlock cycles. The count verification (outside of the pthread_mutex_t structure) suffices and that is retained.
