Similar issue already reported by syzkaller here: https://lore.kernel.org/netdev/ZyIgRmJUbnZpzXNV@calendula/T/#mf1f03a65108226102d8567c9fb6bab98c072444c related to smc->clcsock_release_lock. I think this is a false possible lockdep considers smc->clcsock_release_lock is a lock of the same class sk_lock-AF_INET. Could you please advise? Thanks. Hi Pablo,Thank you for the reminder. We are currently working on it. The community has already submitted some fixes[1], and we are still reviewing them. Best wishes, D.
