Linux 6.4 正式發布！

Linus Torvalds 發布了最新的 Linux 6.4，新版針對 F2FS、Btrfs 檔案系統進行改進，並針對 LoongArch 龍芯架構最佳化效能。

以下來自 Linus 大神的信件內容：

Hmm. Final week of 6.4 is done, and we've mainly got some netfilter
fixes, some mm reverts, and a few tracing updates.

There's random small changes elsewhere: the usual architecture noise,
a number of selftest updates, some filesystem fixes (btrfs, ksmb),
etc.

Most of the stuff in my mailbox the last week has been about upcoming
things for 6.5, and I already have 15 pull requests pending. I
appreciate all you proactive people.

But that's for tomorrow. Today we're all busy build-testing the newest
kernel release, and checking that it's all good. Right?
