Re: [PATCH net v3 2/4] net: hsr: shrink seqnr_lock to sequence counter updates

[Ali Ahmet Memis]

I audited all seqnr_lock users after the change: it now guards only the
sequence counter updates (handle_std_frame() and the two supervision
builders), so dropping the outer lock around hsr_forward_skb() cannot
race any other state. Lock and unlock stay balanced on every path.
