Following the precedent in commit 061c0aa740d5 ("ipv4: igmp: annotate data-races around im->users"), we annotate these intentional data races using READ_ONCE() and WRITE_ONCE() macros. - Patch 1 annotates races around `in_dev->mc_count` (interface-level joins). - Patch 2 annotates races around active timer-related state tracking fields (`tm_running`, `reporter`, `expires`) on individual multicast groups. ==================== Link: https://patch.msgid.link/20260605014318.3890804-1-yuyanghuang@google.com Signed-off-by: Paolo Abeni --- db7a16556f2561bf314a351785b36d7f171f44e7
