Hi all,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/linux/device.h:15,
from include/rdma/ib_verbs.h:43,
from include/rdma/mr_pool.h:8,
from drivers/nvme/host/rdma.c:10:
drivers/nvme/host/rdma.c: In function 'nvme_rdma_create_queue_ib':
drivers/nvme/host/rdma.c:550:24: error: 'idx' undeclared (first use in this function); did you mean 'ida'?
550 | queue->queue_size, idx);
| ^~~
include/linux/dev_printk.h:104:32: note: in definition of macro 'dev_err'
104 | _dev_err(dev, dev_fmt(fmt), ##__VA_ARGS__)
| ^~~~~~~~~~~

Caused by commit

583f69304b91 ("nvme-rdma: use new shared CQ mechanism")

from the rdma tree interacting with commit

5ec5d3bddc6b ("nvme-rdma: add metadata/T10-PI support")

from the block tree.

I applied the following merge fix patch.
