[PATCH 1/3] kthread: update s390 cmm driver to use kthread

[PATCH 1/3] kthread: update s390 cmm driver to use kthread

[Serge E. Hallyn]

Update the s390 cooperative memory manager, which can be a module,
to use kthread rather than kernel_thread, whose EXPORT is deprecated.

This patch compiles and boots fine, but I don't know how to really
test the driver.

Just tried the patch and tested cmm. Still works fine. Patch added to my
"things-that-will-go-out-after-2.6.18" list of patches.

Heiko just pointed out that this has already been fixed. His patch
depends on another patch (oom-killer) and can be found in the current
-mm tree. I'll drop this patch.

NACK.  Please do a real conversion to the kthread paradigm instead of
doctoring around the trivial bits that could be changed with a script.

Please use kthread_should_stop() and remove the cmm_thread_wait
waitqueue in favour of wake_up_process.  The timer useage could
probably be replaced with smart usage of schedule_timeout().
Also the code seems to miss a proper thread termination on module
removal.

Great, thanks.

Do you know whether anyone is working on doing a proper update for the
other two patches I submitted, as per Christoph's comments?  I'd be
timit about gutting those drivers to that extent on my own...

thanks,

Ok, the patch in -mm does kthread_stop() on module_exit, but still uses
the timer and cmm_thread_wait.  

I'm not clear what the timer is actually trying to do, or why there is a
separate cmm_pages_target and cmm_timed_pages_target.  So I'm sure the
below patch on top of -mm2 is wrong (it compiles, but I just noticed
2.6.18-rc4-mm2 doesn't boot without this patch either) but hopefully
Heiko or Martin can tell me what would be the right way, or implement
it?

thanks,

2.6.18-rc4-mm2 works fine for me. What configuration and machine setup did
you use?

Hmm, with my standard config it actually boots.  It fails when I turn
off module support.  The guilty config is attached, as well as the
config that boots, and the output when it crashes with the guilty
config.

That looks like the crypto initialization problem. Currently the new
crypto driver only works if you compile it as a module.

Yes, the timer and cmm_thread_wait are there to implement the timed page
pool.

Yes, it is wrong. Trying to "fix" code without understanding it is waste
of time. The while loop in the cmm_thread is supposed to continue until
the target numbers for the standard page pool and the timed page pool
have been reached. Your patch adds a schedule_timeout between every call
to cmm_alloc_pages.

This should be fixed with -mm3. In addition you need this one on top of -mm3:

This patch appears to be actually in -mm3 (at least the git tree I just
fetched), and is does boot fine now.
