30215. The whole point of call_rcu(), synchronize_rcu(), and friends
303 is to wait until all pre-existing readers have finished before
304 carrying out some otherwise-destructive operation. It is
305 therefore critically important to -first- remove any path
306 that readers can follow that could be affected by the
307 destructive operation, and -only- -then- invoke call_rcu(),
