Actually, there is a whole bitmask of values you can use here in order
to selectively turn on or off parts of the debugging code.
See the NFSDBG_* defines in include/linux/nfs_fs.h.

There are similar bitmasks for the RPC, NLM (i.e. lockd) and nfsd
subsystems in include/linux/sunrpc/debug.h, include/linux/lockd/debug.h
and include/linux/nfsd/debug.h. These bitmasks act
on /proc/sys/sunrpc/rpc_debug, /proc/sys/sunrpc/nlm_debug
and /proc/sys/sunrpc/nfsd_debug respectively.

Note as I said earlier, though, this is really designed for debugging
purposes. There are no plans to convert it into an administrative tool.

Cheers,
  Trond
