  • Summary: The LWN Weekly Edition for 2026-06-11 covers a proposal to remove splice() and vmsplice() from the kernel due to a surge of LLM-discovered security bugs in those system calls. The edition also covers BPF loop verification improvements, fanotify updates, and a broader kernel code-removal drive targeting the ax25, ATM, and ISDN subsystems. A related Phoronix item notes that Linux 7.1 development received more patches than usual due to AI coding agents submitting fixes at high volume.
  • Why it matters: Removal of splice() and vmsplice() would break zero-copy I/O workloads that depend on those calls; applications using them should monitor the discussion.
  • Follow-up: Track formal patch series and maintainer decision on splice/vmsplice removal.
