[LTP] [PATCH v3 0/2] Fix cma testing suite permissions

[Andrea Cervesato]

The cma testing suite started to fail on modern systems enabling YAMA.
Unfortunately, using CAP_PTRACE capability for users is not enough to
avoid an EPERM. For this reason, it's better to require root and fix the
whole suite in one shot.
