kernfs: make kernfs_get_inode() public
Move kernfs_get_inode() prototype from fs/kernfs/kernfs-internal.h to include/linux/kernfs.h. It obtains the matching inode for a kernfs_node. It will be used by cgroup for inode based permission checks for now but is generally useful. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
