This doesn't apply, can you resend it?

Applying: RDMA/core: Move the rdma_show_ib_cm_event() macro
error: sha1 information is lacking or useless (include/trace/events/rpcrdma.h).
error: could not build fake ancestor
Patch failed at 0001 RDMA/core: Move the rdma_show_ib_cm_event() macro
hint: Use 'git am --show-current-patch=diff' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
 
I guess in two weeks after the merge window

Thanks,
Jason
