calls, vnops, vfsops, both in /kern, and to individual file systems that
require a vfsop_ array entry.

+ * Userland/kernel interface for Extended File System Attributes
+ *
+ * This code from the FreeBSD POSIX.1e implementation.  While the syscalls
+ * are fully implemented, invoking the VFS vnops and VFS calls as necessary,
+ * no file systems shipped with this version of FreeBSD implement these
+ * calls.  Extensions to UFS/FFS to support extended attributes are
+ * available from the POSIX.1e implementation page, or possibly in a more
+ * recent version of FreeBSD.
