[PATCH 07/13] defer/rcuusage: Provide the reference to synchronous RCU update-side primitives

[SeongJae Park <sj@kernel.org>]

From: SeongJae Park <sj38.park@gmail.com>

'Deadlock Immunity' paragraph prohibits synchronous RCU update-side
primitives within RCU read-side critical section.  This means those in
'RCU Wait-to-Finish APIs' table, but someone might think those as
general RCU update-side primitives like 'rcu_assign_pointer()'.  To make
it clear, provide the reference to the table.
