- What I did

Starting with kernel v6.12, kernel memory TCP accounting is deprecated for cgroups v1. Note: kernel memory TCP accounting is not supported by cgroups v2.

See torvalds/linux@d046ff4

(cherry picked from commit fb2f811)

- How I did it

- How to verify it

- Human readable description for the release notes

Deprecate support for kernel memory TCP accounting (`KernelMemoryTCP`)

- A picture of a cute animal (not mandatory but encouraged)
