[PATCH v5 0/5] nfsd: clean up refcounting in the filecache

[Jeff Layton <jlayton@kernel.org>]

v5:
- drop the SYNC_NONE flush on addition to the LRU
- schedule the laundrette when adding to the LRU
- base laundrette scheduling on having work to do
- fix potential race in NFSD_FILE_LRU handling
- drop comments that mention NFS version

A number of changes in this set, mostly around the LRU handling. I've
done some light testing with it this morning and it seems to be OK.

Jeff Layton (5):
  nfsd: remove the pages_flushed statistic from filecache
  nfsd: reorganize filecache.c
  nfsd: rework refcounting in filecache
  nfsd: close race between unhashing and LRU addition
  nfsd: fix up the filecache laundrette scheduling
