Apologies for my laziness.
The changes are mainly nits, e.g., small refactorings, additional
comments, etc.; relatively major ones are:
* VM_BUG_ON() -> VM_WARN_ON_ONCE()
* Removed `depends on !MAXSMP`
There are no bug fixes or structural changes in v11. I do have a bug
fix [1] queued for the coming v12, which I have been benchmarking on
top of 5.19-rc1. So far I see no improvements or regressions, compared
with v10 on top of 5.18-rc1.
