memfd_create03 can be found failing with the same error message (this test requires 4.14+), I will update the bug title and description.
** Summary changed: - pkey01 and futex_wake04 from ubuntu_ltp_syscalls failed with X-kvm (Fail to open /proc/sys/vm/compact_memory for writing) + pkey01, futex_wake04 and memfd_create03 from ubuntu_ltp_syscalls failed with X-kvm (Fail to open /proc/sys/vm/compact_memory for writing) -- You received this bug notification because you are a member of Canonical Platform QA Team, which is subscribed to ubuntu-kernel-tests. https://bugs.launchpad.net/bugs/2046148 Title: pkey01, futex_wake04 and memfd_create03 from ubuntu_ltp_syscalls failed with X-kvm (Fail to open /proc/sys/vm/compact_memory for writing) Status in ubuntu-kernel-tests: New Bug description: This issue pops up after updating to the latest tip of LTP test suite (commit 776b57984 "rwtest: Remove df symlink check") These 2 failures are limited to X-kvm kernel and they're all failing with the same error message, I didn't see this failure on other 4.4 variants (X, X-aws, T-lts-X).
