Subject[PATCH v4 7/9] parisc/perf: open access for CAP_SYS_PERFMON privileged process
From
Date

Open access to monitoring for CAP_SYS_PERFMON privileged processes.
For backward compatibility reasons access to the monitoring remains open
for CAP_SYS_ADMIN privileged processes but CAP_SYS_ADMIN usage for secure
monitoring is discouraged with respect to CAP_SYS_PERFMON capability.
