Bug Description

Failed test cases : hugemmap01 hugemmap02 hugemmap04 hugemmap05 hugemmap05_1 hugemmap05_2 hugemmap05_3 hugemmap06 hugeshmat01 hugeshmat02 hugeshmat03 hugeshmat04 hugeshmat05 hugeshmctl01 hugeshmctl02 hugeshmctl03 hugeshmdt01 hugeshmget01 hugeshmget02 hugeshmget03 hugeshmget05

However, if you run this test suite directly, all these test will pass.
So I think this is caused by some other failures before the hugetlbfs test.

Closing this bug as this does not exist in our hint database and we didn't see this issue in recent cycles.

There is a new hugetlb failure after recent LTP update, which will be recorded separately.
