Re: [PATCH] kernel/sched.c - Use the task state macros provided in include/linux/sched.h

[Ryan Bradetich <rbradetich@uswest.net>]

Hello all,

I am working on a a kernel janitor project to use the task state
macros provided in the include/linux/sched.h instead of setting the
task state directly.  Ingo suggested I bring the discussion to this
list to see if this janitor project is still valid, or the best way
to impliment this project.

The entire kernel janitor thread can be found here:
http://sourceforge.net/mailarchive/forum.php?thread_id=908916&forum_id=2314


Thanks,

- Ryan
