Re: [RFC PATCH glibc 1/4] glibc: Perform rseq(2) registration at nptl init and thread creation (v4)

* Mathieu Desnoyers:

Now that I think about it, it's important to move the rseq registration
done at nptl init (in my current code) to some lower-level csu initialiation,
so applications that happen _not_ to link against libpthread also get
registered rseq for the main thread.

Yes.  In general, we want to avoid to force libraries which do not
create threads to link against libpthread, and try to provide interfaces
which are required for synchronization within libc.

Thanks,
Florian
