Subject: [PATCH 0/2] follow-up to 9p: fix race issue in fid contention.

In case anyone wondered why the patch series isn't in -next yet, I ran into
some troubles with non-none cache that the second patch appears to fix.

Also realized I hadn't sent the fixups I had meant Jianyong Wu to do, so
sending both now (keeping it a separate patch) and will put to my next
tree now, this time for real.

Hopefully not too many other bugs not uncovered... But only one way to
find out, and I think refcounting 9p fid will allow some nice
optimizations in the future if anyone cares to work on it...

Onto fscache now...!
