__relay_reset

函数名称：__relay_reset - reset a channel buffer*@buf: the channel buffer*@init: 1 if this is a first-time initialization* See relay_reset() for description of effect.

函数原型：static void __relay_reset(struct rchan_buf *buf, unsigned int init)

返回类型：void

363

count of sub-buffers produced 等于0

364

count of sub-buffers consumed 等于0

uffer has been finalized 等于0

367

start of current sub-buffer 等于start of channel buffer

368

current offset into sub-buffer 等于0
