There is an endianess problem with /proc/sys/fs/nfs/nsm_use_hostnames

  # modprobe lockd nsm_use_hostnames=1
  # cat /proc/sys/fs/nfs/nsm_use_hostnames

The nsm_use_hostnames variable is declared as "bool" which is required
for the correct type for the module parameter. However, this does not
work correctly with the entry in the /proc filesystem since this
currently requires "int".

Jia He already provided patches for this problem a couple of years ago,
but apparently they felt through the cracks and never got merged. So
here's a rebased version to finally fix this issue.

Jia He (2):
   sysctl: introduce new proc handler proc_dobool
   lockd: change the proc_handler for nsm_use_hostnames

Thanks for picking them up ;-)
