函数名称：ring_buffer_has_space
函数原型：static __always_inline bool ring_buffer_has_space(unsigned long head, unsigned long tail, unsigned long data_size, unsigned int size, bool backward)
返回类型：bool
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| unsigned long | head | |
| unsigned long | tail | |
| unsigned long | data_size | |
| unsigned int | size | |
| bool | backward |
| 142 | 如果非backward则返回:Return space available, 0..size-1. We always leave one free charas a completely full buffer has head == tail, which is the same asempty. (head, tail, data_size)大于等于size |
| 144 | 否则返回:Return space available, 0..size-1. We always leave one free charas a completely full buffer has head == tail, which is the same asempty. (tail, head, data_size)大于等于size |
