Re: [PATCH v4 0/2] Create specific kconfig for kselftest

There is a discussion about improving the usability of kselftest by
creating test-specific kconfig in recent kernel Summit. The first
three versions could be found at [1], [2], [3].

Patch 1 keep test-specific kconfig fragments inside each selftest so
that merge_configs.sh could build up a kernel configuration that can
test the specific or all feature(s).

Patch 2 add config option(kselftest-merge) in make file as a
helper to merge all the test config dependecies to .config.

Hi Michal,

Are you okay with the changes to the second patch
in this series? Would you like to me to send the
second one up through linux-kselftest tree or do
you want to take this through your tree?

Please let me know.

thanks,

Changes since v3:
1.  move the target kselftest-mergeconfig from scripts/kconfig/Makfile
    to toplevel Makefile. And rename to kselftest-merge to avoid the
    conflict with "%config" target.

Changes since v2:
1.  Fix the misuse of objtree and srctree in the
    kselftest-mergeconfig target.

Changes since v1:
1.  Add kselftest-mergeconfig in scripts/kconfig/Makefile according
    to the suggestion from Michael.
