Why not just pass in ~0UL as max_size if you want the entire file? > -int kernel_read_file_from_path_initns(const char *path, void **buf, > - loff_t *size, loff_t max_size, > - enum kernel_read_file_id id) > +extern int kernel_pread_file_from_path_initns(const char *path, void **buf, extern? really? i'm shocked gcc doesn't vomit on that.
