That is an obvious bug in the test, the value of run should be restored
only if we managed to change it.
We should do at least:
diff --git a/testcases/kernel/mem/ksm/ksm05.c b/testcases/kernel/mem/ksm/ksm05.c
index f3bfbf4fa..6deaa8440 100644

I've pushed a slightly different patch that fixes the issue:
https://github.com/linux-test-project/ltp/commit/ffc8005a002ecc6f0d70675f7dee79cd481acffc
Thanks for the report.
