4IBM Corporation allowed LGPLv2.1+ licensing of their contribution to the
5userspace RCU library.

7ACCESS_ONCE(), likely(), unlikely() and barrier() are considered trivial enough
8that copyright does not apply to them. I (Mathieu Desnoyers) re-typed them from
9scratch in a mail client just to prove it.

11Bert Wesarg <bert.wesarg@googlemail.com> approved LGPL relicensing of his patch.

13xchg() primitives has been rewritten from a MIT-licensed cmpxchg for Intel and
14powerpc. They are MIT-licensed and therefore usable in LGPL code.
15
16I am therefore permitted to relicense the userspace RCU library as LGPLv2.1.
