- The father of Linux was finally persuaded: the 30-year-old Linux kernel C language will be upgraded to C11
- There has been news recently, and it is exciting that the 1989 version of the C language Linux kernel that has been used has finally received a major upgrade. The pace of contemporary technology is unstoppable. Today, the Linux open source community announced a compelling plan to upgrade the C language version of the kernel to the C11 standard. It is expected that this major reform will take effect after version 5.18 of Linux, which is the upcoming May. This important move will bring unlimited potential opportunities to the Linux kernel and help it better adapt to the needs of modern technologies. This decision was sudden. It only took a week from initiating the question to the official statement. You must know that it is not easy to convince Linus Torvalds, the stubborn father of Linux.

- Linux kernel memory recycling mechanism: in-depth understanding of memory management
- Have you ever encountered various memory problems in Linux systems? Such as memory leaks, memory fragmentation, etc. These problems can be solved by in-depth understanding of the Linux kernel memory recycling mechanism. No matter how much memory there is on the computer, it is not enough, so the Linux kernel needs to reclaim some rarely used memory pages to ensure that the system continues to use memory. There are three methods of page recycling: page writeback, page exchange and page discarding: If the backing storage of a rarely used page is a block device (such as a file mapping), the memory can be directly synchronized to the block device to free up the page. The page can be reused; if the page does not have backing storage, it can be swapped to a specific swap partition and handed over when accessed again.
