2008-05-19RCU, rculist.h: fix list iteratorsPaul E. McKenney
RCU list iterators: should prefetch ever be optimised out with no side-effects, the current version will lose the barrier completely.

2008-05-19rculist.h: use the rcu APIFranck Bui-Huu
Make almost all list mutation primitives use rcu_assign_pointer(). The main point of this being readability improvement. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Cc: "Paul E.

2008-05-19rcu: split list.h and move rcu-protected lists into rculist.hFranck Bui-Huu
Move rcu-protected lists from list.h into a new header file rculist.h. This is done because list are a very used primitive structure all over the kernel and it's currently impossible to include other header files in this list.h without creating some circular dependencies. For example, list.h implements rcu-protected list and uses rcu_dereference() without including rcupdate.h. It actually compiles because users of rcu_dereference() are macros. Others RCU functions could be used too but aren't probably because of this. Therefore this patch creates rculist.h which includes rcupdates without to many changes/troubles.
