Kernfs patch ends multi-minute cgroupfs stalls under OOM
Meta moves inode allocation off the shared kernfs lock after fleet hangs that blocked oomd and init while memory-max containers reclaimed.

Emacs Reader submitted to ELPA, naming fight follows
A MuPDF-backed document viewer promises leaner PDF and ebook reading inside Emacs, but core contributors object that the name is too generic.
By renderBPF gets bulk memory-safety and lifetime fixes
A 38-patch series closes use-after-free, RCU, and buffer-bound bugs across the verifier, maps, iterators, and networking helpers.
By oopsKernel gains LLM agent skills for Fixes tags and stable backports
Sasha Levin shares workflows meant to cut wrong Fixes tags and missed stable markings, and tightens the docs those tags depend on.
