This series addresses issues related to hugepage requirements in the MM selftests, ensuring tests are skipped rather than failing when the necessary hugepage count is not met. This adjustment allows for a more graceful handling for systems with insufficient hugepages, preventing unnecessary test failures and improving the overall robustness of the test suite. This patch (of 3): 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.
