So according to the official page on Hotpatching (without any trackers like in the article), this reminds me of kpatch. I guess Microsoft really wants to spend the effort of making that work. Isn't kpatch not really supported (without $$$) by many larger distros since it's prone to break easily?

Isn't the concept of kernel live-patching just "wait until the kernel's not using that module, and slip in anupdatesd version"

I don't know about Windows, on Linux it's at the function level, and some cases are tricky.

I found more info: Microsoft SQL Server Engine already does hot patching and I guess the same way will be used in other MS apps: https://techcommunity.microsoft.com/t5/Azure-SQL-Database/Hot-Patching-SQL-Server-Engine-in-Azure-SQL-Database/ba-p/849700
