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: keep track of the max and average time to search the cache nfsd: keep stats on worst hash balancing seen so far fs/nfsd/cache.h | 1 + fs/nfsd/nfscache.c | 144 ++++++++++++++++++++++++++++++++++++++++++++++------- fs/nfsd/nfsctl.c | 9 ++++ 3 files changed, 137 insertions(+), 17 deletions(-) -- 1.7.11.7
