Some CPU architectures are able to run with a number of different base-page sizes; using a larger size can often result in better performance at the cost of increased memory use. Other architectures are more limited. At the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, two sessions in the memory-management track explored options for letting processes run with 64KB page sizes when the underlying kernel does not. The first was focused on letting each process have its own page size, while the second concerned bringing 64KB pages to x86 systems.

Paul Gevers has slipped an interesting bit of news into a "bits from the release team" message:

Aided by the efforts of the Reproducible Builds project, we've decided it's time to say that Debian must ship reproducible packages. Since yesterday, we have enabled our migration software to block migration of new packages that can't be reproduced or existing packages (in testing) that regress in reproducibility.

As Gioele Barabucci pointed out, "reproducible" in this sense is limited to building within an instance of Debian's build environment, which is a tighter requirement than is normally used. It is still a big step forward for reproducible builds.

Linus has released 7.1-rc3 for testing. "I think this answers the 'is 7.1 continuing the larger size pattern that we saw with 7.0?' question, and the answer is yes: that wasn't a fluke brought on by a .0 release - it simply seems to be the new normal."
