23 * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 08/08/2000
24 * - reorganize kmallocs in ray_attach, checking all for failure
25 * and releasing the previous allocations if one fails
26 *
27 * Daniele Bellucci <bellucda@tiscali.it> - 07/10/2003
28 * - Audit copy_to_user in ioctl(SIOCGIWESSID)
