Currently, VA exhaustion is being checked by passing a hint to mmap() and
expecting it to fail. This patch makes a stricter test by successful write()
calls from /proc/self/maps to a dump file, confirming that a free chunk is
indeed not available.

Commit c72a870926c2 added a mutex to prevent kunit tests from running
concurrently. Unfortunately that mutex gets locked during module load
regardless of whether the module actually has any kunit tests. This
causes a problem for kunit tests that might need to load other kernel
modules (e.g. gss_k

The sigbus-wp test requires the UFFD_FEATURE_WP_HUGETLBFS_SHMEM flag for
shmem and hugetlb targets. Otherwise it is not backwards compatible
with kernels <5.19 and fails with EINVAL.
