Any progress on figuring out this issue?
Not really; I still can't reproduce it. Sorry for the lack of communication,
but I've been fixing other stuff whilst only occasionally hacking on this.
Anyway, here's a debugging patch that might help. Note that I don't think
this is really a kslowd problem per se. I think it's just happening within
the slow work processing function.
Once the slow work function has blocked for a long time, if you can do:
keyctl add user fscache:objlist KB @s
cat /proc/fs/fscache/objects >/tmp/object-list.txt
and then mail /tmp/object-list.txt to me.

Patch applied and the output file you requested.
Let me know what else I can provide to help out.
