[PATCH v13 15/35] fs: Export anon_inode_getfile_secure() for use by KVM

[Sean Christopherson]

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.
