New Revision: 266293
URL: http://svnweb.freebsd.org/changeset/base/266293
Log:
- Add support for dumping current resource usage for processes via a new -r
flag to procstat.
- Add an -H flag to request information about threads rather than processes
when dumping statistics. Currently it is only used for -r to display
resource usage for individual threads instead of the entire process.
