Linus Torvalds merged a pull request into the Linux kernel on Thursday, removing the Integrated Services Digital Network (ISDN) subsystem and various other outdated network drivers. The pull request noted that old code, including amateur radio and NFC support, has burdened core networking developers for years. Phoronix first reported the changes.
Linus Torvalds, the Linux kernel maintainer, integrated a pull request on Thursday that eliminates the ISDN subsystem from the kernel codebase. This subsystem, part of early digital telephony technology, along with other legacy components, is now deprecated and removed to streamline development efforts. The pull request explicitly states, 'Old code like amateur radio and NFC have long been a burden to core networking developers.'
