The comment [1] suggested that the panic is triggered during page aging.
I think only with an out-of-tree patch applied https://jpbrucker.net/git/linux/commit/?h=sva/2021-03-01&id=d32d8baaf293aaefef8a1c9b8a4508ab2ec46c61 which probably is not going upstream. Thanks, Jean
vfio_pci_mmap() sets the VM_PFNMAP for the VMA and I see in the Documentation that pages with VM_PFNMAP are added to the unevictable LRU list, doesn't that mean it's not subject the page aging? I feel like there's something I'm missing. [1] https://lore.kernel.org/kvm/BY5PR12MB37642B9AC7E5D907F5A664F6B3459@BY5PR12MB3764.namprd12.prod.outlook.com/ (local) Thanks, Alex
