Hi Bruce, The original motivation for this work was to add per-export stats. While doing so, I noticed that most nfsd stats variables are not protected against concurrent update, so fixed that first. There are still a couple stats variables (longest_chain*) that are not counters so less trivial to fix. I did not touch them. There is also an eyebrow raising number of variabled in nfsd_stats struct that are never updated. I did not touch those either. If you want me to send a cleanup patch to remove them and print hardcoded zeroes in the nfsd stats file I can do that. Thanks, Amir.
