Farewell ISDN, Ham Radio and Old Network Drivers: Linus Merges 138k LOC Removal (www.phoronix.com)

In a significant move for the Linux community, Linus Torvalds has merged a major patch that removes 138,161 lines of obsolete network driver code from the Linux kernel. This decision was prompted by AI-driven bug reports highlighting the burdensome nature of maintaining drivers for outdated hardware, which included support for devices like ISDN, legacy Ethernet adapters, and even amateur ham radio configurations. As technology evolves, the need for support of hardware that has long since lost relevance became increasingly clear, leading to the streamlined kernel now seen in version 7.1. By eliminating these outdated drivers, the Linux kernel not only reduces its overall size but also enhances its performance and security. The removal affects a range of old networking technologies, including the 3com 3c509 and AMD Lance drivers, and signals a shift towards a more efficient codebase supported by modern hardware. With the advancement of AI and large language models aiding in code analysis, this update reflects a growing trend where legacy support is being reconsidered in favor of prioritizing current technologies, ultimately benefiting developers and users alike.
