[Bridge] [PATCH tip/core/rcu 10/14] bridge/br_mdb: Apply ACCESS_ONCE() to avoid sparse false positive
From: "Paul E. McKenney" <paulmck at linux.vnet.ibm.com>
The sparse checking for rcu_assign_pointer() was recently upgraded
to reject non-__kernel address spaces. This also rejects __rcu,
which is almost always the right thing to do. However, the use in
__br_mdb_del() is legitimate: They are assigning a pointer to an element
from an RCU-protected list, and all elements of this list are already
visible to caller.
This commit therefore silences these false positives by laundering
the pointers using ACCESS_ONCE() as suggested by Eric Dumazet and Josh
Triplett....
