Module Name: src Committed By: jruoho Date: Fri Apr 13 07:05:32 UTC 2012
Modified Files: src/distrib/sets/lists/tests: module.mi src/tests/modules: Makefile t_modload.sh Added Files: src/tests/modules/k_helper3: Makefile k_helper3.c Log Message: Add a helper program that loads a module and returns the errno from modctl(8). XXX: As noted on tech-kern@, the syscall should be modified to fail consistently with a given predefined errno on non-MODULAR kernels.
