The patch titled
Subject: userfaultfd: selftest: don't error out if pthread_mutex_t isn't identical
has been removed from the -mm tree. Its filename was
userfaultfd-selftest-dont-error-out-if-pthread_mutex_t-isnt-identical.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andrea Arcangeli <aarcange@xxxxxxxxxx>
Subject: 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.
