To make all of these projects happy at once, move the kobject KOBJ_ADD
uevent to just before sending the MODULE_STATE_LIVE notification.

Hello,
Starting from kernel 5.8 all non-optimized kretprobes don't work. Until 5.8,
when #DB exception was raised, entry to the NMI was not fully performed. Among
others, the following logic was executed:
https://elixir.bootlin.com/linux/v5.7.19/source/arch/x86/kernel/traps.c#L589
if
imize such functions when they are padded with INT3?

Agreed.

Hello,
I believe that the following commit does introduce a gentle "functionality
bug":
"module: delay kobject uevent until after module init call":
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/kernel/module.c?id=38dc717e97153e46375ee21797aa54777e5498f3
