类型参数名称
struct task_struct *task
gfp_tgfp
602  buffer等于kmalloc(PAGE_SIZE, GFP_KERNEL)
603  如果非buffer则返回:NULL
606  res等于get_cmdline() - copy the cmdline value to a buffer.*@task: the task whose cmdline value to copy.*@buffer: the buffer to copy to.*@buflen: the length of the buffer. Larger cmdline values are truncated* to this length.
607  buffer[res]等于'\0'
610  当res先自减大于等于0且buffer[res]恒等于'\0'循环
614  以i小于等于res循环如果buffer[i]恒等于'\0'则
616  buffer[i]等于' '
619  quoted等于Return an allocated string that has been escaped of special characters* and double quotes, making it safe to log in quotes.
