[PATCH v2 0/5] nfsd: add a reply_cache_stats file to nfsd for tracking DRC performance

[Jeff Layton <jlayton@redhat.com>]

This patchset adds some stats tracking to the DRC to hopefully allow
us to make better-informed decisions in the future on performance
improvements.

Some of these I've already posted, but reposting them now as a set
to allow Bruce to more easily merge them. I think these would be good
for 3.9, but they're obviously not critical.

Jeff Layton (5):
  nfsd: break out comparator into separate function
  nfsd: track memory utilization in the DRC
  nfsd: add new reply_cache_stats file in nfsdfs
  nfsd: report length of the longest hash chain in reply cache stats
  nfsd: keep track of the max and average time to search the cache
