> The test however reports that this is not happening.

> Error - hugepage files for memtest1 were not deleted!
> Error in test_file_prefix()
> Test Failed
> bash# ls /dev/hugepages/ #hugetlbfs is mounted on /dev/hugepages
> memtest1map_0  memtest1map_1  memtest1map_2  memtest1map_3 
> memtest1map_4  memtest1map_5  memtest1map_6  memtest1map_7 
> memtest1map_8  rtemap_0

> To me it appears that the hugepages are in fact not being deleted 
> correctly.
> Is this an anomaly or is anyone else seeing this issue as well?
