[ltt-dev] [PATCH RFC urcu 0/2] allow multiple URCU flavors in one executable

[Paul E. McKenney]

Hello!

The following pair of patches permits a single executable to use
multiple flavors of URCU without resorting to linker tricks.  The
approach is to map each flavor to a different namespace.  The patches
are as follows:

1.	Provide pthread_atfork-friendly interfaces.
2.	Map symbols to allow multiple flavors of URCU to be mixed.

This does not yet centralize pthread_atfork() handling, nor does it
yet map defer_rcu() and friends.

Thoughts?

							Thanx, Paul
