ipv6: mcast: annotate data-races around mca_users
/proc/net/igmp6 walks IPv6 multicast memberships under RCU and prints
mca_users without holding idev->mc_lock, while multicast join and leave
paths update the field while holding idev->mc_lock. Annotate this
intentional lockless snapshot with READ_ONCE() and the matching writers
with WRITE_ONCE().
