About "realtime" build failure

Hi,

I applied patches which are the effort of various people.
And I could overcome configuration error and keyctl01's build error. (Thanks!!)
After that, librttest.c build failed:
------------

"realtime" became to be build by the patch of Makefile:

"realtime" added to build.
Perhaps this revision caused this failure, I think.

DOTS is garbage, bitrotted code. If no one has any opposes the
change, then I'll remove it from LTP in 3 days time. Thanks,

"DOTS" and "realtime" make failed in above log.

I looked for difference between The "Makefile" of old git (ltp-7e2cbbd.tar.gz)

I tried to make the recent git with the old git's "Makefile". And it succeeded.

I understand.
How about "realtime"? Is "realtime" test necessary in LTP "run test" ?

If "realtime" is necessary, they need revises.
If it is necessary and prospect to its revise are not in sight, it had better to be filtered again, and be removed filtering at revision, I think.
Sorry to bother you when you're so busy.
