Module Name: src
Committed By: pooka
Date: Tue Nov 9 15:25:20 UTC 2010
Modified Files:
src/tests/rump/rumpkern: Makefile
Added Files:
src/tests/rump/rumpkern: t_copy.c
Log Message:
Test copystr/copyinstr/copyoutstr focusing on the off-by-one cases.
As a notable caveat, this does not test the remote RPC paths of
those routines, which are arguably a little more complex.
