Hi Team,

If anyone is help me with below build error message,

git clone https://github.com/linux-test-project/ltp.git
$ cd ltp

That's just a LTP kernel module build failure, the modules we have in
LTP does not support all kernel versions and may fail to build. This is
not treated as an error by the build system and when the module fails to
build the test is skipped when tests are executed.
