Linux Kernel: Filesystem Modernization and Boot Memory Groundwork
This cycle centers on filesystems, with ext4 adding an optional buffered iomap path, B-T-R-F-S removing legacy space cache code, and NTFS and exFAT landing extensive hardening fixes. Paired with that is rework of handover, kexec, and memblock boot-memory handling plus steady architecture maintenance.

It's October 26th, 2026, and this is your Linux Kernel briefing.
The lead signal is filesystems trading legacy code for performance and corruption resistance, while early boot memory handling gets cleaner and more predictable.
First, filesystems. Ext4, in merge ac5feaa, introduces an optional buffered iomap path for regular files, not enabled by default. Large writes show significant gains, but the mode excludes inline data, encryption, verity, journaled data and online defrag, falling back automatically when needed. Developers should…
Second, boot and memory plumbing. Live update, in merge 126ad89, renames kernel handover scratch memory to boot memory, including the kernel command line parameter, to reflect its role in the target kernel. Kexec, in merge b3593ab, keeps the next kernel off hardware poisoned pages and makes image probing distinguish…
Finally, architecture upkeep without behavior change for most users. Parisc fixes EEPROM bounds reads and drops redundant page table helpers, Super-H modernizes two boards off legacy platform data and fixes interrupt controller sorting and I-R-Q teardown, and MIPS fixes huge T-L-B handling and Octeon device tree…
What's next is practical:…
