简介
在linux的代码里有一个注释如下；
If softirq window is exhausted then punt. 少个逗号，加上 If softirq window is exhausted, then punt.
使用bing翻译是：如果 softirq 窗口用尽，则 punt。
这里的punt没有翻译出来。这一句的灵魂就在于punt，结果没有翻译出来。
static __latent_entropy void net_rx_action(struct softirq_action *h) {
。。。。。 /* If softirq window is exhausted then punt. * Allow this to run for 2 jiffies since which will allow * an average latency of 1.5/HZ. */ if (unlikely(budget <= 0 || time_after_eq(jiffies, time_limit))) {
sd->time_squeeze++; break; } 这就没办法了，就只能查字典
字典

解释
另一个
static int try_charge_memcg(struct mem_cgroup *memcg, gfp_t gfp_mask, unsigned int nr_pages) {
。。。。 /* * If the hierarchy is above the normal consumption range, schedule * reclaim on returning to userland. We can perform reclaim here * if __GFP_RECLAIM but let's always punt for simplicity and so that * GFP_KERNEL can consistently be used during reclaim. @memcg is * not recorded as it most likely matches current's and won't * change in the meantime. As high limit is checked again before * reclaim, the cost of mismatch is negligible. */ do {
bool mem_high, swap_high; 另一个
踢悬空球，踢回去。直接返回的意思。
static int affine_move_task(struct rq *rq, struct task_struct *p, struct rq_flags *rf, int dest_cpu, unsigned int flags) {
。。。。 if (task_running(rq, p) || READ_ONCE(p->__state) == TASK_WAKING) {
/* * MIGRATE_ENABLE gets here because 'p == current', but for * anything else we cannot do is_migration_disabled(), punt * and have the stopper function handle it all race-free. */ stop_pending = pending->stop_pending; if (!stop_pending) pending->stop_pending = true;
