When we convert an RO volume to an RW, currently we just copy the
copyDate and creationDate from the RO metadata into the RW. But the
copyDate and creationDate fields have different meanings for RW and RO
volumes: for ROs, the creationDate is merely the last time the data
was updated from the RW during a release operation.
So, if the copyDate is older than the creationDate, use the copyDate
as the new RW creationDate instead. This will probably not match the
creationDate of the original RW, but it will be closer to it, and it
will more accurately represent the conceptual "created time" of the
new RW.
Doing this can avoid forcing an unnecessary full dump on a subsequent
release of the resultant RW volume, since the creationDate is more
accurate.

The Netbios NCBRESET command resets all of the Netbios state
associated with the LAN adapter including the name bindings.
In response to a detected LAN adapter IP address change, the
smb_LanAdapterChange() function is called to determine if any
Netbios LAN adapter bindings that were in use or should be in
use by afsd_service were altered. As part of the check,
lana_GetUncServerNameEx() is called which in turn calls
lana_FindLoopback() which in turn issued a lana_IsLoopback()
for each LAN adapter with the 'reset adapter' flag set to TRUE.
Calling lana_IsLoopback() with 'reset' equal TRUE was fine
when lana_GetUncServerNameEx() was only called from smb_Init(),
but it is not fine when called after the service is processing
calls. By resetting the adapter the binding of the netbios name
"AFS" (or "<MACHINE>-AFS") is removed and all outstanding calls
are canceled. If the SMB redirector attempts a reconnect during
the window before NCBADDNAM is called to re-bind the name, a
negative cache entry will be placed in the netbios name lookup
table that will prevent the SMB redirector from connecting to
the client for several minutes.
If the environment is one in which frequent IP address change
events are triggered, it is possible that the SMB redirector
will never be able to reconnect to the service.
This patchset adds a flag, LANA_NETBIOS_NO_RESET, to the
lana_GetUncServerEx interface which permits smb_LanAdapterChange()
to avoid the undesirable reset. This negative flag was selected
in order to avoid changing the current default behavior as the
lanahelper library is used by out of tree installers and it
is preferred that OpenAFS avoid breaking them unnecessarily.

Try to avoid this by returning the RX_CALL_TIMEOUT error when we get a

avoid using the same call channel again where possible. When all of
