Please fix this fucking selftests shit to just build. This is unusable garbage.
I don't recall all the reasons why kselftests needed "make headers" One reason I could think of was that when a new test depends on a header change, the test won't build unless headers are installed.
...or until an updated copy of that updated header file is copied somewhere, and then included in the kselftests. That's the approach that I ultimately settled upon, after some discussion and negotion.
Details below.
If this requirement is causing problems for tests that don't fall into the category and we probably have more of them mow, we can clean that up.
John, you mentioned you got mm tests working without headers? Can you share the commit here.
Yes. This one sets up the general approach, which is available to all kselftests: TOOLS_INCLUDES. It also changes selftests/mm to set TOOLS_INCLUDES in that build:
e076eaca5906 ("selftests: break the dependency upon local header files")
And here is a representative application of the above, to selftests/mm. In other words, taking advantage of the new file location pointed to by TOOLS_INCLUDES:
580ea358af0a ("selftests/mm: fix additional build errors for selftests")
thanks,
