struct page结构本身就占有一定内存,如果struct page结构设计过大,那么本身就会占用较多内存,而给系统或者用户可用的内存就较少,所以对strcut page结构大小非常敏感,即使增加一个字节 对系统影响也会非常大,故社区对struct page的结构做了严格设计,不会轻易增加字段: One of these structures exists for every physical...

iobuf_create_stdalloc_arena (iobuf_pool); 1. 该函数并没有为arena分配缓冲区用的大块内存空间。如果在用的时候找不到合适大小的iobuf,则动态建立一个。 2、iobuf_pool的使用,主要是两个函数: struct iobuf * iobuf_get2 (struct iobuf_pool *iobuf_pool, size_t page_size); ...
