The other affected package is ocaml-mdx, fixed by [PATCH v2] send to
patch#62796.

Considering these 2 patches, the OCaml packages in core-updates build
fine.  Except ocaml-uring with the error:

--8<---------------cut here---------------start------------->8---
 # let `Timeout, timeout = consume t;;
-val timeout : int = -62
+val timeout : int = -22
--8<---------------cut here---------------end--------------->8---

Well, the errno -62 is expected and corresponds to -ETIME from Linux
kernel documentation.  All documented in tests/main.md of the package
ocaml-uring,

--8<---------------cut here---------------start------------->8---
## Timeout

Timeout should return (-ETIME). This is defined in 
https://github.com/torvalds/linux/blob/master/include/uapi/asm-generic/errno.h#L45

```ocaml

[...]

# let `Timeout, timeout = consume t;;
val timeout : int = -62
--8<---------------cut here---------------end--------------->8---

And I do not understand why this -22 (EINVAL Invalid argument).  Any
idea?
