SVN rev 216271 on 2010-12-07 22:00:48Z by trasz
MFC r216084:
Don't panic when we read an empty ACL from ZFS. Apparently this may happen
with filesystems created under MacOS X ZFS port. This is kind of filesystem
corruption (we don't allow for setting empty ACLs), so make acl_get_file(3)
and related syscalls fail with EINVAL in that case. In theory, we could
return empty ACL to userland, but I'm afraid this would break some code.
