Hi all,

I'm running the 6.7.0-rc8-00174-g95c8a35f1c01 kernel from torvalds tree on a Ubuntu 23.10 Mantic Minotaur system.

What I get are these errors. memfd selftests are actually counted as "ok", but they give errors and/or hang.

Please find the strace output attached, and the config used.

Hope this helps.

Best regards, Mirsad
