Linux kernel 6.12-rc1 released
So two weeks have passed, and rc1 is out - the merge window is closed.
Despite conference travel (both for me and several maintainers), things seemed to go mostly fairly normally. There's a couple of notable new features in here: For one thing, PREEMPT_RT is now mainlined and enabled as a config option (you do need to enable "EXPERT" to get the question). For another, sched_ext also got merged.
That said, the bulk is - as always - all the plain old regular updates, and that obviously means drivers dominate. We've got about 55% of the patch being drivers (and another 5% if you count the dts files). Add in 5% doc updates, and 10% tooling (mostly perf and selftests).
That leaves about a quarter of the overall changes as core kernel code, split between arch updates, filesystems (yes, bcachefs, but also btrfs, smb sever and client, netfs updates, xfs and finally core VFS updates mostly in the form of 'struct fd' re-organisational cleanups). And MM, core networking, Rust, security layer updates etc.
A little bit of everything, in other words. And nothing really looks all that strange. As always, the summary below is just the log of my merges, there's too much to list individually (some stats: 11k+ regular commits, 850+ merges, 1700+ different authors).
Let's get the testing and calming down period started, ok?
