hi

Today, the O(1) seems to be quite incompatible with Tux. Will you be
merging these two together, or is that a no-go?

thanks

sure, i'll merge them. There are no big conceptual issues. I think the
only thing that needs to be done is to change the ->cpus_allowed setting
to set_cpus_allowed().

Not usre if its a bug or my fault.
To build bproc, I changed all

nice = current->nice -----> nice = task_nice(current)

but...

werewolf:~# depmod -ae
depmod: *** Unresolved symbols in /lib/modules/2.4.18-pre7-slb/bproc/bproc.o
depmod: task_nice

Perhaps a missing

EXPORT_SYMBOL(set_user_nice);
+EXPORT_SYMBOL(task_nice);

in ksyms.c ??

TIA
