Re: [PATCH] fuse: mark DAX VMA page protections as decrypted

Hi Pankaj,

Thanks for looking into this! Yes, that makes sense - virtio-fs DAX support 
(the DAX window BAR) was developed in out-of-tree QEMU development branches 
(e.g., https://github.com/rhvgoyal/qemu or https://gitlab.com/virtio-fs/qemu) 
and was never fully merged into upstream mainline QEMU.

In our case, we validated the guest kernel DAX driver on AMD SEV-SNP and Intel TDX 
hardware using our in-house lightweight VMM coupled with the standalone Rust virtiofsd 
daemon. Other public VMMs like Cloud-Hypervisor [1] and crosvm [2] also support 
the DAX shared memory window natively.

I have posted a [PATCH v2] to the list incorporating your Acked-by tag.

Thanks again for the review and assistance!
