函数名称:iocg_kick_waitq
函数原型:static void iocg_kick_waitq(struct ioc_gq *iocg, struct ioc_now *now)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct ioc_gq * | iocg | |
struct ioc_now * | now |
1145 | struct iocg_wake_ctx ctx = {iocg = iocg} |
1152 | lockdep_assert_held( & lock) |
1154 | current_hweight(iocg, NULL, & hw_inuse) |
1158 | abs_vdebt等于atomic64_read( & abs_vdebt) |
1159 | vdebt等于Scale @abs_cost to the inverse of @hw_inuse. The lower the hierarchical* weight, the more expensive each IO. Must round up. |
1161 | delta等于min_t - return minimum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(u64, vbudget, vdebt) |
1166 | atomic64_add(delta, & done_vtime) |
1167 | atomic64_sub(abs_delta, & abs_vdebt) |
1168 | 如果WARN_ON_ONCE(atomic64_read( & abs_vdebt) < 0)则atomic64_set( & abs_vdebt, 0) |
1181 | 如果WARN_ON_ONCE(vbudget >= 0)则返回 |
