Man page updates will be done as separate commits.

Hey Rick,
The patch review test plan mentions a patch to ZFS itself to support
named attributes. Is that patch available somewhere?
Thanks,
I am a little confused but the features seem to be there even if I do

Create a new ZPool and then a ZFS filesystem with xattr=on :
titan# camcontrol devlist
