[PATCH] Fix bug in RCU torture test
While doing some test of RCU torture module, I hit a OOPS in rcu_do_batch, which was trying to processes callback of a module that was just removed. This is because we weren't waiting long enough for all callbacks to fire. Signed-off-by: Srivatsa Vaddagiri <vatsa@in.ibm.com> Cc: Dipankar Sarma <dipankar@in.ibm.com> Acked-by: "Paul E.
