Subject: [musl] Backwards kernel compatibility

--0000000000007a0a2105c1f35cae
Content-Type: text/plain; charset="UTF-8"

Hello guys,

I'd like to ask, if it is generally supported to run recent musl on older
kernels? My primary concern is that there are new syscalls being added to
linux, while at the same time I do not see a switch similar to glibc's to
select compatibility mode (--enable-kernel). Is there some means which
prevent invocation of unimplemented syscalls on older kernels when using
musl?

Best regards,
Martin Vajnar
