>Description:
Hi,

when trying to umount pool/some/dataset and zfs(8)
fails because pool/some/dataset/inside is also
mounted, then it fails with error message that
refers to umount(1M) instead of umount(8).

  # zfs umount pool/some/dataset
  cannot unmount 'pool/some/dataset': legacy mountpoint
  use umount(1M) to unmount this filesystem

There are actually LOTS of such references, just type:

  # grep -r -E " [a-z]+\(1M\) " /usr/src

Regards,
vermaden
>How-To-Repeat:
# zfs umount pool/some/dataset
cannot unmount 'pool/some/dataset': legacy mountpoint
use umount(1M) to unmount this filesystem

# grep -r -E " [a-z]+\(1M\) " /usr/src
>Fix:
1. Find all 'foreign' references with:
   # grep -r -E " [a-z]+\(1M\) " /usr/src

2. Update/change them to our local ones, for example:
   umount(1M) --> umount(8)
