[PATCH v2 2/2] selftests/perf_events: Test FASYNC with watermark wakeups.

by Kyle Huey

The test uses PERF_RECORD_SWITCH records to fill the ring buffer and trigger the watermark wakeup, which in turn should trigger an IO signal.

[PATCH] selftests/mm: Dont fail testsuite due to a lack of hugepages

by Nico Pache

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.
