Hi, what LTP version are you running? Can you check if it has following commit: https://github.com/linux-test-project/ltp/commit/a2d159595a761da1626b3f489dfe9cf2c351b774 Regards, Jan > > > > Regards, > Ramesh > > > ------------------------------------------------------------------------------ > October Webinars: Code for Performance > Free Intel webinars can help you accelerate application performance. > Explore tips for MPI, OpenMP, advanced profiling, and more.
