I would say it is very possible. There was a period when the pool

I don't know which version Yi Zhang was using. The root cause of this
bug was caused by
librdmacm making verbs API calls while holding _irqsave locks which I
didn't figure out until later.
Hi Bob,
I can reproduce the issue Yi reported with kernel v5.18-rc1. Please let
me know if you need any additional information to reproduce this issue.
Thanks,
Bart.
