New Revision: 295677
URL: https://svnweb.freebsd.org/changeset/base/295677
Log:
Fetch the current thread and it's syscall state from the trussinfo object
instead of passing some of that state as arguments to print_syscall() and
print_syscallret(). This just makes the calls of these functions shorter
and easier to read.
