    [readdir] introduce ->iterate(), ctx->pos, dir_emit() · bb6f619b
    Al Viro 提交于
    New method - ->iterate(file, ctx).  That's the replacement for ->readdir();
    it takes callback from ctx->actor, uses ctx->pos instead of file->f_pos and
    calls dir_emit(ctx, ...) instead of filldir(data, ...).  It does *not*
    update file->f_pos (or look at it, for that matter); iterate_dir() does the
    update.
    
    Note that dir_emit() takes the offset from ctx->pos (and eventually
    filldir_t will lose that argument).
