Linus has released 6.1-rc1 and closed the
merge window for this development cycle.

This isn’t actually shaping up to be a particularly large release:
we “only” have 11.5k non-merge commits during this merge window,
compared to 13.5k last time around. So not exactly tiny, but
smaller than the last few releases. At least in number of commits.

That said, we’ve got a few core things that have been brewing for a
long time, most notably the multi-gen LRU VM series, and the
initial Rust scaffolding (no actual real Rust code in the kernel
yet, but the infrastructure is there).
