X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=ba8dd9533e647b70d6e46beed3dcd8d8036b02af;hp=ba8dd9533e647b70d6e46beed3dcd8d8036b02af;p=nfs-utils.git

If portmap is not listening on UDP (as apparently happens with
MS-Windows-Server2003R2SP2), then nfs mounts have to be mounted
with -o mountproto=tcp to succeed.

In this case a umount will still try UDP and will fail to contact the
server.  It will still succeed with the local unmount (after a
timeout) but exits with a non-zero exit status.  This causes
/bin/mount to retry so we get a strange error about the filesystem
not being mounted.

So:
  get umount to use tcp if "mountproto=tcp" appears in mtab
  ignore any failure message from the server that would overwrite
     a success message from the local umount syscall.
