>Description:
acl_get_link_np(name, ACL_TYPE_NFS4) on any ZFS returns NULL with errno=EINVAL.

As result I have errors in ls -l output like this:
# /bin/ls -ld /
ls: /: Invalid argument
drwxr-xr-x  19 root  wheel  - 25 Sep 29 14:59 /

Also cp -p return 1 and buildworld fails with following messages:
===> share/zoneinfo (all)
cp -p /usr/src/share/zoneinfo/yearistype.sh yearistype
cp: failed to get acl entries while setting yearistype: Invalid argument
*** Error code 1

Also this breaks building of some ports like www/apache22:
configure.in:190: the top level
rebuilding rpm spec file
rebuilding srclib/apr-util/configure

Looking for apr source in /var/ports/usr/ports/www/apache22/work/httpd-2.2.13/srclib/apr
cp: failed to get acl entries while setting build/get-version.sh: Invalid argument
cp: failed to get acl entries while setting build/config.sub: Invalid argument
cp: failed to get acl entries while setting build/config.guess: Invalid argument
cp: failed to get acl entries while setting build/install.sh: Invalid argument
cp: failed to get acl entries while setting build/find_apr.m4: Invalid argument
cp: failed to get acl entries while setting build/apr_common.m4: Invalid argument
./buildconf failed for apr-util
*** Error code 1
>How-To-Repeat:
# zpool create tank `mdconfig -a -t swap -s 64m`
# ls -ld /tank
ls: /tank: Invalid argument
drwxr-xr-x  2 root  wheel  - 2 Oct  2 12:09 /tank/
