There are a few places in the kenrnel which directly de-reference
pointers marked as "noderef" such sa rcu or percpu. In the case
of rcu, one example is:
kernel/fork.c:2146:32: warning: incorrect type in assignment (different
address spaces)
kernel/fork.c:2146:32: expected struct task_struct [noderef] <asn:4>
*real_parent
kernel/fork.c:2146:32: got struct task_struct *task
this looks fairly non-trivial to fix given there's a mix of __rcu and
non-__rcu
attributed variables.
Does anyone have an idea how to go about fixing these, if possible?
