Hey, things continue to look good, and rc3 isn't even very big. I'm hoping there's not another shoe about to drop, but so far this really feels like a nice calm release cycle, despite the size of the merge window.
Anyway, rc3 has a little bit of everything. The biggest single change is actually just a documentation update (the intel pstate docs were converted to rst format), so the diffstat actually looks a bit odd with a wuarter just being documentation. There's also some tooling updates (perf and some bpf selftest).
But if you ignore those two pieces, it looks pretty normal: two thirds of it being drivers (gpu, nvme, scsi, tty, block), with the remainder being about half networking and haf "misc" (core kernel, header files, XFS, arch updates).
