Change Details

I mistakenly implemented semantics for O_NAMEDATTR which were not compatible with what Solaris implements for O_XATTR. This patch fixes 2ec2ba7e232d so that Solaris compatible semantics can be implemented by patched ZFS code.

The Solaris semantics for their O_XATTR flag is to use it for a file object in the file system's namespace to indicate that a named attribute for the file object should be open'd. To do this, the O_NAMEDATTR flag must be allowed with a non-named attribute directory. This patch changes vfs_vnops_cred() to allow this. This patch fixes 2ec2ba7e232d so that Solaris compatible semantics can be implemented by patched ZFS code.
