    To see the effect make sure you have an empty SPD.
    On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush"
    You get prompt back in window1 and you see the flush event on window2.
    With this fix, you still get prompt on window1 but no event on window2.

When no more memory can be allocated, fq_find() will return NULL and
increase the value of IPSTATS_MIB_REASMFAILS. In this case,
ipv6_frag_rcv() also increase the value of IPSTATS_MIB_REASMFAILS.

The RCU usage in the original code was broken because
there are cases where we possibly sleep with rcu_read_lock
held. As a fix, change the macvtap_file_get_queue to
get a reference on the socket and the netdev instead of
taking the full rcu_read_lock.

Also, change macvtap_file_get_queue failure case to
not require a subsequent macvtap_file_put_queue, as
pointed out by Ed Swierk.

with 32 bit userland and 64 bit kernels, it is unlikely but possible
that insertion of new rules fails even tough there are only about 2000
iptables rules.

This happens because the compat delta is using a short int.
Easily reproducible via "iptables -m limit" ; after about 2050
rules inserting new ones fails with -ELOOP.

Note that compat_delta included 2 bytes of padding on x86_64, so
structure size remains the same.

This will cause trouble once CONFIG_COMPAT support is added to ebtables.
xt_compat_*_offset() calculate the kernel/userland structure size delta
using:

XT_ALIGN(size) - COMPAT_XT_ALIGN(size)

If the match/target sizes are aligned at registration time,
delta is always zero.

Should have zero effect for existing systems: xtables uses
XT_ALIGN() whenever it deals with match/target sizes.
