[PATCH 6/8] kern: implement task_set_name |
Date: |
Sat, 1 Feb 2014 15:09:26 +0100 |
task_set_name sets the name of a task. This is a debugging aid. The
name will be used in error messages printed by the kernel.
* kern/task.c (task_set_name): New function.
* kern/task.h (task_set_name): New declaration.
