Hi, This small patch series makes guest_memfd use guest mem inodes instead of anonymous inodes and also includes some refactoring to expose a new function that allocates an inode and runs security checks. This patch series will serve as a common base for some in-flight series: * Add NUMA mempolicy support for KVM guest-memfd [1] * New KVM ioctl to link a gmem inode to a new gmem file [2] * Restricted mapping of guest_memfd at the host and arm64 support [3] aka shared/private conversion support for guest_memfd [1] https://lore.kernel.org/all/20250408112402.181574-1-shivankg@xxxxxxx/ [2] https://lore.kernel.org/lkml/cover.1747368092.git.afranji@xxxxxxxxxx/ [3] https://lore.kernel.org/all/20250328153133.3504118-1-tabba@xxxxxxxxxx/ Ackerley Tng (2): fs: Provide function that allocates a secure anonymous inode KVM: guest_memfd: Use guest mem inodes instead of anonymous inodes fs/anon_inodes.c | 22 ++++-- include/linux/fs.h | 1 + include/uapi/linux/magic.h | 1 + mm/secretmem.c | 9 +-- virt/kvm/guest_memfd.c | 134 +++++++++++++++++++++++++++++++------ virt/kvm/kvm_main.c | 7 +- virt/kvm/kvm_mm.h | 9 ++- 7 files changed, 143 insertions(+), 40 deletions(-) base-commit: a5806cd506af5a7c19bcd596e4708b5c464bfd21 -- 2.49.0.1204.g71687c7c1d-goog
