selftests/membarrier: skip unpermitted membarrier command test if preregistered by libc

2026-08-28T05:50:07+00:00

On thread creation, Musl registers the private expedited memory barrier, see pthread_create [1]. Thus, invoking the barrier command will no longer be rejected by the kernel with EPERM. The test checking this will fail. Check if the memory barrier command has been registered and skip the test in this case.

selftests/membarrier: introduce helper to get membarrier command registrations

2026-08-28T05:50:07+00:00

Patch series "selftests/membarrier: Skip an unregistered memory barrier test on Musl". The membarrier test "membarrier MEMBARRIER_CMD_PRIVATE_EXPEDITED not registered failure" fails in the multithreaded test scenario when using Musl libc as the command gets preregistered implicitly during thread creation. Skip the test if command registration is detected. This patch (of 2): Add a new membarrier_get_registrations() for reusage.
