The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated. Bear in mind that the `%k' and `%b' format specifiers of -printf handle sparse files differ‐ ently. The `b' suffix always denotes 512-byte blocks and never 1 Kilobyte ...
用于打印block_device指针的名称。 struct va_format %pV 用于打印struct va_format结构。它们包含格式字符串和va_list,如下所示: structva_format{ constchar*fmt; va_list *va; }; 实现了“递归vsnprintf”。 在没有某种机制来验证格式字符串和va_list参数的正确性的情况下,请不要使用此功能。 通过引用传递。
