  30  * Userland/kernel interface for Extended File System Attributes
  31  *
  32  * This code from the FreeBSD POSIX.1e implementation.  While the syscalls
  33  * are fully implemented, invoking the VFS vnops and VFS calls as necessary,
  34  * no file systems shipped with this version of FreeBSD implement these
  35  * calls.  Extensions to UFS/FFS to support extended attributes are
  36  * available from the POSIX.1e implementation page, or possibly in a more
  37  * recent version of FreeBSD.
  38  *
  39  * The POSIX.1e implementation page may be reached at:
  40  *   http://www.watson.org/fbsd-hardening/posix1e/
