The libhugetlbfs test suite has various tests for which a failure (under
certain circumstances) is expected and not indicative of an error. It would be
desirable to specially annotate these cases to eliminate the need for the
tester to know which failures are known and which could be bugs.
Thi
quota is known to fail on kernels < 2.6.24. Create a wrapper script to check
for an old running kernel and report the failure as expected. Place reusable
shell functions into their own wrapper-utils.sh script.
Changes since V1:
- Make sure to install wrapper-utils.sh along with tests
Signed-of
Make use of pre-existing kernel version comparison code and create a helper
that can be used by test wrapper scripts to compare two kernel versions.

Oops. The greater-than operator (>) is not commutative. While trying to test
for a > b, we are accidentally re-testing a < b. Fix.

On recent 64-bit Debian systems, /usr/lib64 is a symbolic link to
/usr/lib and 64-bit libraries are installed to /usr/lib/$ARCH-linux-gnu.
In this case, the 64-bit install of libhugetlbfs overwrites the 32-bit
version of the library. It's different in Ubuntu where lib can be the
64-bit directory, l

The current override for the contents of meminfo via a replacement
read_meminfo will not work now that these functions are in a library.
Switch to overriding the files returned from open by overriding that
instead. This is actually a superior way to test as it also allows us
to test the library im
Following this email are two fixes for gethugepagesizes. The first is a
fix to the test suite to repair the test since the move of various routines
into the library. The second fixes the semantics of gethugepages counting
mode which was incorrectly triggering, as detected by the fixed test.
It sh
gethugepagesizes has two modes: a counting mode which tells us exactly
how many entries we would need; and a lookup mode which fills in a
supplied buffer.
The counting mode is defined as triggering when we pass in both a zero
element count and a NULL buffer pointer. Currently we enter this mode w
