Hi Bob,

If I run the following test against Linus' master branch then that test
passes (commit d5ae8d7f85b7 ("Revert "media: dvb header files: move some
headers to staging"")):

Can this commit "RDMA/rxe: Zero out index member of struct rxe_queue"
in the link https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip/jgg-for-rc
fix this problem?

And the commit will be merged into linux upstream very soon.

The only difference between these two tests is that test (1) use the siw
(soft-iWARP) driver while test (2) uses the rdma_rxe driver (soft-RoCE).
Both tests run reliably against previous Linux kernel versions, e.g.
v5.13. Can you take a look at this? The blktests software is available at
https://github.com/osandov/blktests/.

Thanks,

Bart.
