Hi Marek,
Thanks for the bug report. But this is a known issue and Jeff Layton
is working on a patchset that aims to fix it.
http://www.spinics.net/lists/linux-nfs/msg25585.html
Can you please try it out and see if it fixes the issue for you?
[I am wondering why Jeff did not CC LKML while sending the patchset!]
Adding relevant people and linux-pm mailing list to CC.
Thanks,
Srivatsa S. Bhat

Sorry, it was an oversight -- I should have cc'ed LKML. At this point,
the patchset seems to work as expected, but I need to respin it to

I'll be sure to cc LKML when I send the respun set...

Thanks. To be clear, you did have the patchset applied on top of this?
If so, then I wonder if we just hit a race...
freezer_do_not_count() just sets PF_FREEZER_SKIP. It's possible though
that the freezer has already tried to put the task to sleep just before
that flag is set. If so, then the schedule() will run and the task
won't go to sleep.
I suppose we could do a try_to_freeze() prior to going to sleep. I'll
add that in for the coming respin...
