The handling of close_lru in preprocess_stateid_op was a source of some
confusion here recently. Try to make the logic a little clearer, by renaming
find_openstateowner_id to make its purpose clearer and untangling some
unnecessarily complicated goto's.

We're insisting that the lock sequence id field passed in the
open_to_lockowner struct always be zero. This is probably thanks to the
sentence in rfc3530: "The first request issued for any given lock_owner is
issued with a sequence number of zero."
But there doesn't seem to be any problem with allowing initial sequence
numbers other than zero. And currently this is causing lock reclaims from the
Linux client to fail.
In the spirit of "be liberal in what you accept, conservative in what you
send", we'll relax the check (and patch the Linux client as well).

The sequence number we store in the sequence id is the last one we received
from the client. So on the next operation we'll check that the client gives
us the next higher number.
We increment sequence id's at the last moment, in encode, so that we're sure
of knowing the right error return. (The decision to increment the sequence id
depends on the exact error returned.)
However on the *first* use of a sequence number, if we set the sequence number
to the one received from the client and then let the increment happen on
encode, we'll be left with a sequence number one to high.
For that reason, ENCODE_SEQID_OP_TAIL only increments the sequence id on
*confirmed* stateowners.
This creates a problem for open reclaims, which are confirmed on first use.
Therefore the open reclaim code, as a special exception, *decrements* the
sequence id, cancelling out the undesired increment on encode. But this
prevents the sequence id from ever being incremented in the case where
multiple reclaims are sent with the same openowner. Yuch!
We could add another exception to the open reclaim code, decrementing the
sequence id only if this is the first use of the open owner.
But it's simpler by far to modify the meaning of the op_seqid field: instead
of representing the previous value sent by the client, we take op_seqid, after
encoding, to represent the *next* sequence id that we expect from the client.
This eliminates the need for special-case handling of the first use of a
stateowner.

A misreading of the spec lead us to convert all errors on open and lock
reclaims to RECLAIM_BAD. This causes problems--for example, a reboot within
the grace period could lead to reclaims with stale stateid's, and we'd like to
return STALE errors in those cases.
What rfc3530 actually says about RECLAIM_BAD: "The reclaim provided by the
client does not match any of the server's state consistency checks and is
bad." I'm assuming that "state consistency checks" refers to checks for
consistency with the state recorded to stable storage, and that the error
should be reserved for that case.

The Linux PCMCIA code has some data that was apparently used (or meant to be
used) to ensure that only proper client drivers are loaded. This is now
ensured (to a certain degree) by the fact that the most client drivers are
part of the kernel. Also, the version information has not been updated
despite major changes in PCMCIA API. This has made it meaningless.
This patch removes servinfo_t and pcmcia_get_card_services_info. They are not
used in any userspace utilities such as pcmcia-cs and pcmciautils.
drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly.
CS_RELEASE and CS_RELEASE_CODE are removed. include/pcmcia/version.h is empty
now. It will be removed later, but for now it's left in the tree to avoid
touching all PCMCIA clients.
The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c,
which uses CS_RELEASE_CODE.

converted the check_region() calls in drivers/pcmcia/i82365.c into
request_regions. Unfortunately this seems to have broken things.
isa_probe() used to call check_region() and then call add_pcic() which would
request_region().
Now isa_probe() calls request_region() and then calls add_pcic() which calls
request_region() again, this fails and add_pcic() returns immediately without
doing all the setup etc.
On the face of it the patch below fixes the problem, by not doing the second
request region in add_pcic(). I think this is preferable to remove the call
in isa_probe() since identify() touches the I/O regions and is called before
add_pcic().
However I haven't fully grokked the meaning of the code which follows the
request_region() in isa_probe(), so I'm not sure that the handling WRT
multiple sockets and multiple bridge chips is correct. In particular I'm not
convinced that the regions for subsequent sockets and/or bridges will be
requested at all. I suspect a more thorough reworking by someone who
understands what is going on there might be in order.
I should mention that I'm actually messing about with this on an ARM platform
with wacky memory and i/o mapping offsets etc, it doesn't quite work yet for
other reasons which preclude full testing etc, but I think the problem above
is still present for more normal x86 stuff.
