Draft:Kswapd

kswapd is a daemon in the Linux system, and its function is to maintain memory balance in the Linux system In order to enhance system performance and ensure faster response times for each application, the Linux system strives to utilize available system memory efficiently. This includes caching substantial amounts of pagecache and reserving more anon pages, allowing processes to directly access them without the need for real-time triggering of page faults or IO operations to load data. However, due to the finite nature of memory and the ability of applications to open numerous instances, there comes a point when memory becomes exhausted. To address this, the kernel has implemented a set of memory reclamation mechanisms, including kswapd for memory recovery and direct reclamation.
