Presumably looking something like statx(2) (except hopefully with extensible structs this time :P)? I think that could also be useful, but given this is a fairly straight-forward syscall addition (and it also would resolve the AT_EMPTY_PATH issue for chmod as well as simplify the glibc wrapper), I think it makes sense to take this and we can do set_statx(2) separately? -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
