KERNEL HOTFIX BLITZ LANDS 20 MM PATCHES, DESAULNIERS RETURNS TO MAINTAINERS
By RepoJournal · Filed · About Linux · Composed from the cited sources · methodology
Andrew Morton just merged 20 memory management fixes into mainline, with 12 tagged for stable backports and a familiar face reclaiming the clang toolchain desk.
The MM hotfix pull [1] is the heavyweight here: 17 of the 20 patches target memory subsystems, splitting between stable candidates and post-7.1 issues that didn't make the cut for backporting. That's the kind of volume that signals either accumulated debt or a specific problem set someone finally cleared. The DAMON fixes from SJ address genuinely old issues, which is worth noting if you've been sitting on DAMON reliability concerns. The remaining patches include tools/virtio build fixes from Yichong Chen, but the meat is in MM. Meanwhile, Nick Desaulniers is back in the MAINTAINERS file [2], returning to the clang/llvm toolchain role with the kind of commit message that only works in the Linux kernel. This matters if you care about clang compatibility or have been tracking his absence from the desk.
