You can implement something like pthread_once():

Where to put it I don't know. It doesn't belong in include/linux/once.h. I'm okay with arch/x86/kvm/call_once.h and just pull it with #include "call_once.h".
Thanks for the suggestion, I can work with that. As to where to put it, I think the new 'struct once' needs to be a member of struct kvm_arch, so I've put it in arch/x86/include/asm/.
Here's the result with that folded in. If this is okay, I'll send a v2, and can split out the call_once as a prep patch with your attribution if you like.
Has there been any progress here? I'm also affected by the crosvm regression, and it's been backported to the LTS stable kernel.
Would you be able to try the proposed patch here and reply with a Tested-by if it's successful for you? I'd also like to unblock this, whether this patch is in the right direction or try something else.
Sure! I can confirm this patch fixes crosvm for me when applied to 6.13.
