Hello Jens Axboe Could we replace ctx->sq_mask/ctx->cq_mask with cq_ring->ring_mask /sq_ring->ring_mask ? because it’s a constant and never change in io_uring.c
I found that ctx->sq_mask just used on https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/io_uring.c?h=v5.1#n1831 and we can replace like follow: - head = READ_ONCE(ring->array[head & ctx->sq_mask]); + head = READ_ONCE(ring->array[head & ring->ring_mask]); If I understand incorrectly, please point out.
