There is no need to open nonexistent real files if backing files couldn't be backed by real files (e.g., EROFS page cache sharing doesn't need typical real files to open again). Therefore, we export the alloc_empty_backing_file() helper, allowing filesystems to dynamically set the backing file without real file open. This is particularly useful for obtaining the correct @path and @inode when calling file_user_path() and file_user_inode(). Signed-off-by: Hongbo Li <[email protected]>
