Hi,
These are the same changes I send earlier in two parts against 2.6.0-test1.
I remade the diff against 2.6.0-test3 as Stephen Hemminger's patch clashed
with mine (My patch already had the fix....)

changes:
-fix waitqueue oops on interrupted socket call
-add refcounting like struct sock for ax25_cb
-skb allocation uses dev->hard_header_len instead off
predicted worst case.
-ax25_cb list uses hlists like struct sock
-lock sk in ax25_find_listener
-ax25_destroy_timer set from 10*HZ to 2*HZ (Tihomir Heidelberg)
-lock sock when calling ax25_destroy_socket() (Tihomir Heidelberg)
-Set ax25->sk to NULL when destroying sk (Tihomir Heidelberg)
-Empty write_queue in ax25_destroy_socket() (Tihomir Heidelberg)
-ax25_destroy_timer() doesn't share its timer with the heartbeat
timer
-lock sock in ax25_destroy_timer()
-return when destroying ax25 route (Ralf Baechle)
-Add ax25_cb_put() calls to netrom
-Initialize ax25_iface lists to NULL
-unlock linkfail_lock in ax25_linkfail_release()
-unlock listen_lock in ax25_listen_release()
-unlock_listen_lock in ax25_listen_mine()
-remove module_owner from nr_init()
-Only release/register listener in nr_set_mac_address() if
interface is up.
-Call nr_destroy_socket() with socket locked
-Free write queue in nr_destroy_socket()
-Add missing sock_[unlock/release] calls in netrom code
-nr_destroy_tmer set from 10*HZ to 2*HZ
-Fixed net_device refcounting to nr_dev_first() and nr_dev_get()
-Added nr_node & nr_neigh refcounting
-Use hlists for nr_node_list and nr_neigh_list
-Added nr_node locking
-Prevent race between freeing dev.priv and freeing dev
-Don't free dev.name on module exit
-Fix error return value from ax25_connect()
-Missing unlock in ax25_register_sysctl()
-nr_route_frame() makes a private copy of skb's instead of using
the one given, it also reserves head room using hard_header_len
from the device the packet goes out removing the need for
AX25_BPQ_HEADER_LEN
-Make ax25_cb refcounting inlined or macro.
-Additional locking in ax25
