Linux maintainer Linus Torvalds has blocked the inclusion of DAMON (Data Access MONitor) in the Linux kernel by default. The decision was made after a proposal by maintainer Songjae Pak to include DAMON in the standard build of kernel 6.16. The proposal argued that DAMON is already used in Amazon, Android, Debian, and Fedora, and that it would simplify configuration for users. However, Torvalds rejected the proposal, stating that "we don't make random functions enabled by default." DAMON is an optional feature that requires manual configuration by setting CONFIG_DAMON. It was developed with the participation of Amazon and is used to monitor data access for memory optimization. The decision has sparked debate among Linux users, with some arguing that the kernel is not a dumping ground for all features, while others wonder if anyone has actually used DAMON. The Linux community continues to discuss the merits of DAMON and its inclusion in the kernel.
