Hi David,

I would like to discuss my V7 posting for Add NUMA mempolicy support
for KVM guest-memfd (https://lore.kernel.org/linux-mm/20250408112402.181574-1-shivankg@amd.com)
which incorporates feedback (using inodes for storing mempolicy) from my V6 posting.
I believe they're in better shape now.

Thanks,
Shivank
