[SRU][Lunar/Mantic][PATCH 0/1] CVE-2023-6531

[Yuxuan Luo]

[Impact]
Allowing io_uring to send file descriptors over UNIX domain sockets
leads to potential circular referencing which is error-prone for garbage
collectors and has caused lots of problems. The upstream has decided to
disble this feature before it creates more trouble.

[Backport]
It is a clean cherry pick.

[Test]
Compile and boot tested.

[Potential Regression]
Although it certainly breaks existing users, the discussion in the
mailing list believes "it's very low risk"[1].
