I was able to run most of the hwsim tests except few tests (around 20) which are failing due to other reasons which are not relevant to the changes I submitted. But I didn't observe any RCU warnings in my hwsim setup. Not sure if it is due to difference in kernel .config between our setups. I enabled below kernel config additionally to find out RCU warnings but with no luck. It would be very help for me if you can share kernel ".config" from your hwsim setup. CONFIG_RCU_TRACE=y - veeru

I don't think my config as is would be all that useful since I have UML patches too. johanness

I submitted the fix for RCU warning with below patch - https://lore.kernel.org/linux-wireless/20240904015520.3571295-1-quic_vjakkam@quicinc.com/ Also, I submitted v2 for this patch set after some code changes. The above RCU warning not applicable to v2 patch set of this series hence I sent the RCU bug fix as separate fix.
