I have reviewed it. Both series replace .wake_tx_queue in ath11k, so they conflict textually there, but they solve different problems: mine stops -ENOMEM by checking the ring space before dequeue, his adds AQL, airtime fairness and a full deficit round-robin scheduler. The two are complementary. For ath11k, my series is smaller (4 patches, 7 review cycles) and has no external dependencies, so it may be simpler to land first. Julius already offered to rebase onto it in his cover letter [1] and move the ring check into his scheduling round. Since there is no conflict in ath12k (Julius's series is ath11k only), I could split ath11k and ath12k into separate series to try to unblock both. By the way, any more feedback on the ath12k patches? WDYT? [1] https://lore.kernel.org/all/20260908135319.754140-1-julius@bairaktaris.de/ Thanks Best regards José Ignacio
