[PATCH v3 0/4] nfsd: clean up refcounting in the filecache

[Jeff Layton <jlayton@kernel.org>]

There are a number of changes here from the last set, but I've tried to
address Neil and Chuck's comments (thanks for the review, btw).

I think I've solved the race between adding to the LRU and unhashing.
That's in patch #3. We may want to squash that into #2 before merging.

Jeff Layton (4):
  nfsd: remove the pages_flushed statistic from filecache
  nfsd: rework refcounting in filecache
  nfsd: close race between unhashing and LRU addition
  nfsd: start non-blocking writeback after adding nfsd_file to the LRU
