Hi Linus,

Fairly normal pull request. The NFS biovec work to push it down into
RDMA instead of indirecting through a scatterlist is pretty nice to
see, been talked about for a long time now.

There is a small conflict with v6.19:

@@@ -55,11 -54,6 +54,10 @@@ int mana_ib_create_cq(struct ib_cq *ibc
                                                          ibucontext);
                doorbell = mana_ucontext->doorbell;
        } else {
-               is_rnic_cq = true;
 +              if (attr->cqe > U32_MAX / COMP_ENTRY_SIZE / 2 + 1) {

 +                      return -EINVAL;
 +              }
                buf_size = MANA_PAGE_ALIGN(roundup_pow_of_two(attr->cqe * COMP_ENTRY_SIZE));
                cq->cqe = buf_size / COMP_ENTRY_SIZE;
                err = mana_ib_create_kernel_queue(mdev, buf_size, GDMA_CQ, &cq->queue);
