Subject: Re: [PATCH 1/3] sched/wait: use freezable_schedule when possible

Hi Joel,

I'm currently testing these changes. I hope to be able to come back with
more concrete results soon.

Also, I just noticed that the third patch removes a necessary #include
<linux/freezer.h>. I will submit an updated version tomorrow.

Thanks for the review!

regards,
 Hugo
