That is what the test is for, and the check to make it run on previous kernels as well was made a runtime check. Do you expect this to compile on a kernel without the corresponding kernel changes that were committed with this patch?
Anjali
Gentle ping - could you answer above questions?
I am seeing the same on linux-next next-20230727
PROC_EVENT_NONZERO_EXIT is defined and NL_MESSAGE_SIZE
Anjali,
What are the dependent commits and should they be in next? Shouldn't this test patch go with the kernel patches it depends on? Can you do some testing on next and let me know why this test is failing to build?
It is failing for me for sure.
There could be problem in the test Makefile that it isn't including the right headers.
