New Revision: 262690
URL: http://svnweb.freebsd.org/changeset/base/262690
Log:
When querying a process's umask via sysctl in libprocstat(), don't
print a warning if EPERM is returned as this is an expected failure
mode rather than error -- similar to current handling of ESRCH.
This makes the output of 'procstat -as' vastly more palatable.
