stress-ng V0.17.07 "trusty task trasher"

Key Highlights:

• New powmath stressor (power math functions)
• New expmath stressor (exponent math functions)
• New logmath stressor (logarithmic math functions)
• New LSM stressor (exercise Linux LSM lsm_list_modules and lsm_get_self_attr system calls)
• New statmount stressor (exercise Linux statmount and listmount system calls)
• New --fma-libc option to use libc fma functions (if available)
• New --memhotplug-mmap option to exercising mmap/munap during memory hotplugging
• New walking flush vm stressor method to walk through memory doing writes followed by cache flushes
• New --mmap-stressful option to enable all --mmap options to make mmap stressor more stressful

Fixes:

• Porting fixes to support modern Solaris systems
• Improve vecshuf performance (regression due to using -O3 on gcc on vec ops)
