Released this morning is the new Linux 2.6.15.6 stable kernel. The new kernel merely addresses a few issues from the 2.6.15.5 as it doesn't now reset rskq_defer_accept in reqsk_queue_alloc, offers a fs/nfs/direct.c compile fix, mempolicy.c compile fix, makes sure BITS_PER_BYTE is defined, and [IA64] die_if_kernel() can return (CVE-2006-0742). These changes won't largely effect most users, however, they are worth mentioning none the less. The Linux 2.6.15.6 kernel can be found at
