Matthew Dobson 0eaae62aba [PATCH] mempool: use common mempool kmalloc allocator
This patch changes several mempool users, all of which are basically just
wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather
than their own wrapper function, removing a bunch of duplicated code.

Michael Holzheu 5f38433885 [PATCH] s390: fix endless retry loop in tape driver
If a tape device is assigned to another host, the interrupt for the assign
operation comes back with deferred condition code 1.  Under some conditions
this can lead to an endless loop of retries.  Check if the current request is
still in IO in deferred condition code handling and prevent retries when the
request has already been cancelled.

Michael Holzheu 4cd190a736 [PATCH] s390: tape operation abortion leads to panic
When a request is aborted because of a signal, we currently stop the request
via csh, but we do not wait for the interrupt of csh in any case.  We free the
request structure and therefore when the interrupt for the csh operation is
presented, the request object is no longer valid and an invalid callback
pointer is used.

To fix this wait until the interrupt for csh arrives and until
wait_event_interruptible() does not return -ERESTARTSYS.

dasd_cmd just implements three ioctls which are wrappers around functionality
in the core kernel or other modules.  When merging those into dasd_mod they
just add 22 lines of code which is far less than the amount of code removed in
the last two patches, and which doesn't spill into another 4k pages when build
modular, while removing a 128lines module.

those, I've marked them with XXX comments.

Handle ioctls implemented in dasd_ioctl through the normal switch statement
that most drivers use instead of the awkward dasd_ioctl_no_register routine.
This avoids searching a linear list on every call to dasd_ioctl(), and allows
to give the various ioctl implementation functions sane prototypes, aswell as
moving the check for bdev->bd_disk->private_data from the individual functions
to dasd_ioctl.  (I think it can't actually every be NULL, but let's keep that
for later)

(Thus the rport instead of the scsi_host becomes parent of a
scsi_target again.)

(2) Avoid scsi_device allocation during registration of an remote port.
(Would be done during fc_scsi_scan_rport.)

(3) Fix queuecommand behaviour when an zfcp unit is blocked.
(Call scsi_done with DID_NO_CONNECT instead of returning
SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting
for completion in blk_execute_rq for ever.)

Horst Hummel 90f0094dc6 [PATCH] s390: dasd partition detection
DASD allows to open a device as soon as gendisk is registered, which means the
device is a fake device (capacity=0) and we do know nothing about blocksize
and partitions at that point of time.  In case the device is opened by
someone, the bdev and inode creation is done with the fake device info and the
following partition detection code is just using the wrong data.

To avoid this modify the DASD state machine to make sure that the open is
rejected until the device analysis is either finished or an unformatted device
was detected.

Peter Oberparleiter aa88861fc3 [PATCH] s390: dasd reference counting
When using the dasd diag discipline, the base discipline module (eckd or fba)
can be unloaded, even though the dasd driver requires both discipline modules
(base and diag) to work correctly.

Implement reference counting for both base and diag discipline modules in
order to fix this.

Frank Pavlic 15c7369178 [PATCH] s390: V=V qdio fixes
Using FCP devices with V=V support, the input queue stalled when CCQ 97 had
been returned in qdio_do_eqbs.  When this happen we have to reissue the eqbs
instruction.

Another bug was when V=V was enabled we checked if hardware has SIGA-sync
support.  If not we returned with 0 from tiqdio_is_inbound_q_done.  Thus qdio
lost initiative on FCP devices and input queue stalled.  Running devices in
V=V there is no SIGA-sync support but nevertheless we have to process
tiqdio_is_inbound_q_done either.

Cornelia Huck 6d751c43b2 [PATCH] s390: ccw device disbanding
If __ccw_device_disband_start() fails to initiate disbanding, it should finish
with ccw_device_disband_done() (which leaves the device in offline state)
instead of ccw_device_verify_done() (which leaves the device in online state).

Frank Pavlic 66cc5d5aee [PATCH] s390: some qeth driver fixes
[patch 2/2] s390: some qeth driver fixes

From: Frank Pavlic <fpavlic@de.ibm.com>
	- fixed kernel panic when using EDDP support in Layer 2 mode
	- NULL pointer exception in qeth_set_offline fixed.
	- setting EDDP in Layer 2 mode did not set NETIF_F_(SG/TSO)
	  flags when device became online.
	- use sscanf for parsing and converting IPv4 addresses
	  from string to __u8 values.
	- qeth_string_to_ipaddr6 fixed. in case of double colon
	  the converted IPv6 address out from the string was not correct
	  in previous implementation.

[patch 1/2] s390: lcs performance enhancements

From: Klaus Wacker <kdwacker@de.ibm.com>
	- When flood pinging (with large packet size) an LCS device,
	  about 90 % of all packets are dropped by driver.
	- increased number of lcs IO buffers to 32.
	- use netif_stop_queue/netif_wake_queue in lcs_start_xmit routine
	- don't lock the whole xmit routine but just the piece of code where
	  tx_buffer is touched.
