Hello, this is Linux Kernel Daily for the week of October 19 through October 26, 2026.
Quick stats: 0 pull request activity items, 30 additional commits this week.
Our lead insight: this was a merge-window week for kernel 7.4, with filesystems delivering new behavior and the boot memory stack getting safer and clearer, while older architectures got maintenance.
First, filesystems. In commit 390febb, B-T-R-F-S removes the old version 1 free-space cache, disabled last release. If you still relied on it, expect behavior equivalent to no space cache, with the newer free-space tree as the path forward. In commit ac5feaa, E-X-T-4 adds optional buffered input-output mapping…
Second, boot, kexec and memory management. Commit 126ad89 renames K-H-O scratch memory to K-H-O boot memory, including the kernel command line option, to reflect use in the target kernel rather than cold boot. If you boot with that option or test live update, update scripts now. Commit b3593ab makes kexec probing…
Third, mature architectures. Commit 6b4b543 for Parisc fixes bounds checks in the expansion bus enumerator and drops redundant page-table helpers. Commit 44dc57e for Super-H modernizes board input and…
