If anyone has any objections, please let me know. ------------------ From: Raf Dickson [ Upstream commit 4ff2e84ff1b33d79fa0e3ae355ce4a334908ef9a ] Replace the open-coded backlog check with sk_acceptq_is_full(). The helper uses > instead of >=, which is the correct comparison per commit 64a146513f8f ("[NET]: Revert incorrect accept queue backlog changes."), and adds READ_ONCE() for proper memory ordering.
