函数名称:Change the queue depth of the iolatency_grp. We add/subtract 1/16th of the* queue depth at a time so we don't get wild swings and hopefully dial in to* fairer distribution of the overall queue depth.
函数原型:static void scale_change(struct iolatency_grp *iolat, bool up)
返回类型:void
参数:

---|---|---|
struct iolatency_grp * | iolat | |
bool | up |
367 | qd等于 Max # of requests |
368 | scale等于scale_amount(qd, up) |
374 | 如果up则 |
375 | 如果old恒等于1且blkcg_unuse_delay(lat_to_blkg(iolat))则返回 |
384 | 否则 |
名称 | 描述 |
