Similar to the Yorktown policy, Watson searches the size tree and finds the smallest possible block suitable for the request.
与Yorktown策略相似，Watson搜索大小树，寻找符合请求的最小的块。
Ext2fs is designed for block devices like IDE devices, where the logical block size will be on the order of 512 bytes, 1 kilobyte, and so on.

A programmer can specify a buffer size - sending to a buffered channel will not block unless the buffer is full, and reading from a buffered channel will not block unless the buffer is empty.
程序员可以指定缓冲大小——想缓冲的channel发送消息不会阻塞，除非缓冲已满，同样从缓冲的channel读取也不会阻塞，除非缓冲是空的。
