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? All the commits went in together - however, the kernel changes that went in this patch need to be *installed on kernel on which this is being built*. Did you do that and then try? Jakub, Do I need to revert the -f runtime filter option back to compile time and commit with that disabled so the selftest compiles on a kernel on which the new options are not defined?
