* 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.
*
* The POSIX.1e implementation page may be reached at:
