Hi Naresh, This doesn't fail gracefully when a regular user runs it. Please add a check for root and make the test fail gracefully when a non-root user runs it. Please refer to tools/testing/selftests/efivarfs/efivarfs.sh for an example on how to check for root. I was getting ready to apply this to linux-kselftest next for 4.3 and ran some sanity tests. If you get me new revision quickly I can get it into 4.3-rc1. thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Open Source Innovation Group Samsung Research America (Silicon Valley) shua...@osg.samsung.com | (970) 217-8978 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
