These patches fixes trivial errors with building
and running DAMON selftests.

[PATCH 1/2] selftests/damon: add damon to selftests root Makefile

[Yuanchu Xie]

Currently the damon selftests are not built with the rest of the
selftests. We add damon to the list of targets.

[PATCH 2/2] selftests/damon: make selftests executable

[Yuanchu Xie]

The damon selftests do not have the executable bit on. We fix that by
setting the x bits on the .sh files similar to other existing shell
selftests.

This type of change does not work outside of git, so why not just make
the tool that calls these scripts not care about the executable bit like
we do for other scripts?

Actually, we made kselftest receives scripts having no executable bit[1],
though it still prints warning.  I guess Yuanchu wants to remove the warning?

To remove the warning, simply making kselftest (runner.sh) stop printing the
warning message might make more sense.  Nevertheless, it's also true that
letting some scripts have executable bits while others not looks inconsistent
to me.  That's why I left the warning message there.  Should we remove the
warning from kselftest and remove executable bits from other selftest test
scripts?  Or, let the inconsistency be?  I have no real opinion here, so just
wanted to hear others' opinion if possible.

BTW, similar issue is also in Kconfig's 'shell' macro.  For example,
'runst-version.sh' on -mm tree bothered me before[2], and now
'pahole-version.sh'.  I might make change in 'scrips/Kconfig/preprocess.c'
later.

I don't recall why we decided to add the check in runner.sh - let's keep them
consistent with the rest of the scripts. If we get rid of the check, we can
make the change then.

It seems reasonable to add the x bit for these tests to be consistent with
the rest.

I also received an email from a patchwork-bot+linux-kselftest@kernel.org
telling me my patch series was included in shuah/linux-kselftest.git, but
that does not seem to be the case.
Is this a bug?

Sorry about the previous non-plain-text email. I never replied to anyone
before and didn't know what I was doing.
