"../../../../usr/include/" directory doesn't have header files if

easy and correct for other build combinations as well?
Hi Muhammad,
I just pulled linux-next, and tried with KHDR_INCLUDES. It works. Very nice
work! I really appreciate you made headers inclusion compatible. However,
my case is a little more complicated. It will throw warnings with -I, using
-isystem can suppress these warnings, more details please refer to
https://lore.kernel.org/all/C340461A-6FD2-440A-8EFC-D7E85BF48DB5@xxxxxxxxxx/
According to this case, do you think will it be better to export header path
(KHDR_INCLUDES) without “-I”?
Well said. I've thought about it and it seems like -isystem is better
than -I. I've sent a patch:
https://lore.kernel.org/linux-kselftest/20220214160756.3543590-1-usama.anjum@xxxxxxxxxxxxx/
I'm looking forward to discussion on it.
The patch has been accepted. It should appear in linux-next soon. You
should be able to use KHDR_INCLUDES easily now.
Sherry,
I pulled in your patch as a fix as is for 5.17-rc5.
Using KHDR_INCLUDES can be separate patch for next release.
This way the fix is going to be pulled for this release
without dependencies on other patches.
thanks,
