I'll add this to the commit desc then when applying. The commit that added this to the deny list said: 31f4f810d533 ("selftests/bpf: Add fexit_sleep to DENYLIST.aarch64") ``` It is reported that the fexit_sleep never returns in aarch64. The remaining tests cannot start. ``` So, if the lack of Ftrace direct calls would be the reason then the failure would be due to fexit programs not being supported on arm64. But this says that the selftest never returns therefore is not related to ftrace direct call support but another bug? Thanks, Puranjay
