From b1a529bdb9641392b4f5fc91545598793c0b3b96 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 5 Jun 2025 22:34:31 +0100 Subject: [PATCH] selftests/mm: skip failed memfd setups in gup_longterm Unlike the other cases gup_longterm's memfd tests previously skipped the test when failing to set up the file descriptor to test. Restore this behavior to avoid hitting failures when hugetlb isn't configured.
