[RFC][PATCH] identify rcu-protected ptr

[Suzanne Wood]

Please consider an addition to the patch to identify
raid rcu-protected pointer occurences.  All of the
work in the raid submittals which is correct is that
of Paul McKenney and any errors and oversights are
mine.

Also, please consider the effective addition of an
rcu_dereference() in bpq_get_ax25_dev() in recognition 
of each use being nested in an rcu critical section.
Thank you.
