This Kselftest update for Linux 5.4-rc1 consists of several fixes to existing tests and adds KUnit, a lightweight unit testing and mocking framework for the Linux kernel from Brendan Higgins.
So I pulled this, but then I almost immediately unpulled it.
My reason for doing that may be odd, but it's because of the top-level 'kunit' directory. This shouldn't be on the top level.
The reason I react so strongly is that it actually breaks my finger memory. I don't type out filenames - I auto-compete them. So "kernel/" is "k<tab>", "drivers/" is "d<tab>" etc.
It already doesn't work for everything ("mm/" is actually "mm<tab>" not because we have files in the git tree, but because the build creates various "module" files), but this breaks a common pattern for me.
In the future KUnit will be linked to Kselftest framework to provide a way to trigger KUnit tests from user-space.
Can the kernel parts please move to lib/kunit/ or something like that?
Please also move the top-level Kconfig menu item "KUnit support" to somewhere that is not top-level. Maybe also in the lib/ menu. Maybe in lib/Kconfig.debug.
