| |
Export anon_inode_getfile_secure() so that it can be used by KVM to create and manage file-based guest memory without need a fullblow filesystem. The "standard" anon_inode_getfd() doesn't work for KVM's use case as KVM needs a unique inode for each file, e.g. to be able to independently manage the size and lifecycle of a given file.
Note, KVM doesn't need a "secure" version, just unique inodes, i.e. ignore the name.
