Linux Movable Zone: Explained and Enabled

Linux does not enable the 'movable' zone by default, but it can be configured through kernel parameters. This special memory area allows its content to be moved or reallocated for other processes or kernel use. It's often employed for memory defragmentation and dynamic memory allocation. In specific scenarios, the 'movable' zone can enhance system performance and availability. Even though it's disabled by default, the 'movable' zone still exists in Linux, ready to support particular applications.
