Log:
SVN rev 199189 on 2009-11-11 15:43:07Z by jh
Create verifier used by FreeBSD NFS client is suboptimal because the
first part of a verifier is set to the first IP address from
V_in_ifaddrhead list. This address is typically the loopback address
making the first part of the verifier practically non-unique. The second
part of the verifier is initialized to zero making its initial value
non-unique too.
This commit changes the strategy for create verifier initialization:
just initialize it to a random value. Also move verifier handling into
its own function and use a mutex to protect the variable.
This change is a candidate for porting to sys/nfsclient.
