I noticed a long time ago that the thread information in
/proc/net/rpc/nfsd isn't updated anymore since somewhere between the
2.629 (information present) and 2.6.32 (information missing). It's
quite easy to check:
# grep th /proc/net/rpc/nfsd
th 8 0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000
All values are perpetually at zero. Unsurprising, because the
update_thread_usage function in fs/nfsd/nfssvc.c isn't present anymore.
I can't find any information about why this information was dropped; I
personnally found it useful to tune properly the number of nfs threads
on loaded servers. Did it use up too many resources? In that case,
could there be a mechanism to enable or disable therad information
gathering, for instance through writing to some /proc file?
