Do you remember the first time you used the Linux system? Like everyone else, maybe you have a painful installation experience, perhaps you also use FIPS or partition magic to increase your hard disk space, perhaps you have been cautious, scary, afraid of their own misoperation caused by the hard drive system necrosis. You often get headaches for doing this in a little-known Linux system, but now there is a

Both the wait queue header and the Wait queue item contain a list_head type of domain as a "join". It
