Hello,
I recently had the case where a test fails with something like this:
FAIL : hugeshmget01 call failed - errno = 38 : Function not implemented
This shows up as I don't use CONFIG_HUGETLBFS in my kernel.
Maybe this has already been discussed but how about including kernel
config headers into LTP to avoid such irrelevant report?
Thoughts?
Attached is a small patch I tried in order to turn the FAILURE into N/A.
If the functionality is not present in the kernel, the program simply exits.
Before compiling, one must copy <kernel root>/include/linux/autoconf.h
into <ltp root>/include .
The compilation is conditional. At LTP root, issue:
USE_KNL_CONFIG=y make
