Hi Naman/Salvatore,

Is it possible to get this fixed in the 6.1 LTS series too? I just ran
into this crash when moving from bookworm based Debian kernel
6.1.153-1 to 6.1.158-1. I saw that "uio_hv_generic: Let userspace take
care of interrupt mask" appeared in 6.1.156.

Thanks,
Peter.

Hi Peter,
Yes, I have sent a patch for older kernel versions as well.
I am working to fix the review comments and send new revisions.
