Subject: [RHEL7 PATCH 05/31] tests: truncate-above-4GB: Skip if truncation
|
|
point is not aligned
|
|
|
|
Attempting ftruncate() on a hugetlbfs file descriptor requires
|
|
the truncation point to be aligned to the huge page size. So,
|
|
this test is not applicable for huge page sizes greater that
|
|
are either greater than or not a factor of the truncation point.
