From 6d47e74e217501e9fd8b1a60a916bc44a2bb683a Mon Sep 17 00:00:00 2001 From: Brendan Jackman Date: Fri, 21 Feb 2025 18:25:42 +0000 Subject: [PATCH] selftests/mm: skip uffd-stress if userfaultfd not available It's pretty obvious that the test wouldn't work if you don't have the feature enabled. But, it's still useful to SKIP instead of failing so the reader can immediately tell that this is the reason why.
