Hello,
We have a patch which adds sunrpc /proc entries without having to enable the
full SUNRPC debug, which we found useful. Tested on NVIDIA Tegra30.
Many thanks,
Thomas

If we want /proc/sys/sunrpc the current kernel also drags
in other debug features which we don't really want. Add the
option for the entries by adding CONFIG_SUNRPC_DEBUG.
/proc/sys/sunrpc/max_resvport
/proc/sys/sunrpc/min_resvport

/proc/sys/sunrpc/nfs_debug
/proc/sys/sunrpc/nlm_debug
/proc/sys/sunrpc/rpc_debug

Can we hide the nfsd_debug, nfs_debug, nlm_debug, and rpc_debug entries under
CONFIG_SUNRPC_DEBUG, but still show everything else?

I don't think we need a new Kconfig option for this, do we? Let's just show the
proc entries unconditionally.
Thanks,
