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.

Hi Zhu,

Thanks for having taken a look.

Isn't commit cc4f596cf85e ("RDMA/rxe: Zero out index member of struct
rxe_queue") already in Linus' tree? I think it was merged yesterday (August
24). Unfortunately the test I mentioned still fails on top of that patch.

Thanks,

Bart.
