Subject: [PATCH] selftests/mm: Dont fail testsuite due to a lack of hugepages
Date: Fri,  1 Mar 2024 00:33:00 -0700

On systems that have large core counts and large page sizes, but limited
memory, the userfaultfd test hugepage requirement is too large.

Exiting early due to missing one test's requirements is a rather aggressive
strategy, and prevents a lot of other tests from running. Remove the
early exit to prevent this.

Fixes: ee00479d6702 ("selftests: vm: Try harder to allocate huge pages")
