kcsan: Fix misreporting if concurrent races on same address If there are at least 4 threads racing on the same address, it can happen that one of the readers may observe another matching reader in other_info. To avoid locking up, we have to consume 'other_info' regardless, but skip the report. See the added comment for more details. Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Paul E.
