New Revision: 319520
URL: https://svnweb.freebsd.org/changeset/base/319520
Log:
Decode the 'who' argument passed to getrusage().
Add a new sysdecode_getrusage_who() which decodes the RUSAGE_* constant
passed as the first argument to getrusage(). Use this function in both
kdump and truss to decode the first argument to getrusage().
