Wait, I misread your previous post. The compiler uses cdecl by default, so
unless you specify NTAPI then you get cdecl

Yeah I get that, and I realise the change is wrong. (I blindly followed the
headers). I just wanna understand it before I revert.
What I don't get is that if I were to write code which uses this API, I
would write my callbacks without NTAPI as per the headers. I'm guessing
most other devs would too. So how are people building with cdecl and being
called by Windows with stdcall without stack issues?
In fact, explicitly going against the DDK and adding NTAPI to your callbacks
would generate a compiler warning.

MS DDK often misses NTAPI, since the compiler uses it by default.
So unless there is a __cdecl in the DDK definition, your change is most
likely wrong.
PS: I guess it's time to finally autogenerate headers at build time, so that
nobody even gets tempted to hack ntifs/ntddk/wdm/winnt directly instead of
adding stuff to XDK... :)

Well this is a weird one, the DDK says these callbacks
are cdecl
(missing
NTAPI) and anyone building against the DDK will obviously declare their
callbacks to match this convention. However internally, windows uses
stdcall for these callbacks.
I can't find much by way of problems people have encountered with
this, so
why aren't people seeing problems with the way the stack is cleaned
up?
Anyone have any ideas before I blindly revert this change?
