[AUDIT]
ntoskrnl/ex (according to functions_list.txt in audited branch comments by Alex Ionescu, and uuid.c comments by me) - dbgctrl.c: Modified the function slightly for compatibility with some keys, still has nothing to do with Windows' - lookas.c: File is clean. I merely rewrote existing versions based on a GPLed IBM driver I found on google, OSR documentation and some DDK sample code. The implementation is trivial and only calls caller-defined functions which are the ones doing the work. - uuid.c: Added programmers, unified formatting, STDCALL->NTAPI change. Code doesn't look suspicious, plus stubbed functions - win32k.c: Alex Ionescu only changed the functions to call Win32K instead of having the code in ntoskrnl. It was a cut/paste job. Aleksey Bragin: The code looks very trivial and straightforward, certainly it's written based on clean sources of information - zone.c: Based on David Welch's code, which Alex Ionescu merely cleaned up, using clean development. He's not even sure if the Zone functions are still in Windows. svn path=/trunk/; revision=21930
