Besides that, we can also print the time zone in its UTC offset representation with the %z format: $ date +%z +0200 The offset tells us that the current system time zone is 2 hours ahead of the UTC. 5. timedatectl For all of the Linux distro that comes with systemd, the timedatectl...

s performance. Each connection takes memory and CPU to track and manage them. While it’s theoretically possible to have many sockets open, the underlying host would need the resources to manage these effectively. On Linux hosts, we can query that limit in the file/proc/sys/fs/file-max. ...

在主调度函数__schedule()中,如果任务prev因为IO阻塞,即prev->in_iowait不为0而调度出去,这时候就会调用delayacct_blkio_start()将当前时间戳记录下来: current->delays->blkio_start = ktime_get_ns() 而在这个阻塞任务由于IO资源可用而被唤醒时,内核调用delayacct_blkio_end()函数将这段阻塞睡眠的时间累加到...
