Zhang Rui 91a6902958 sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes
Well, first of all, I don't want to change so many files either.

What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.

In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(

Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)

Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.

Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

Tejun Heo 7b595756ec sysfs: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

Michael Loehr 9f28745a6b [SCSI] zfcp: IO stall after deleting and path checker changes after reenabling zfcp devices
IO stall after deleting and path checker changes after reenabling zfcp device

Setting one zfcp device offline using chccwdev in a multipath
environment and waiting will lead to IO stall on all paths.
After setting the zfcp device back online using chccwdev,
the devices with io stall will have a different path checker.
Devices corresponding to the deleted units are never freed.
This has the effect that 'slave_destroy' is never called and zfcp
still thinks that this unit is registered
(ZFCP_STATUS_UNIT_REGISTERED is still set). Hence the erp
routine is not called correctly and the unit is not enabled properly.

Do not delete rport and the sdev. Just set the host to block on
'offline'. Setting host online again will then remove the blocked status
and everything is fine again.

Christof Schmitt 5f852be9e1 [SCSI] zfcp: Fix deadlock between zfcp ERP and SCSI
The SCSI stack requires low level drivers to register and
unregister devices. For zfcp this leads to the situation where
zfcp calls the SCSI stack, the SCSI tries to scan the new device
and the scan SCSI command fails. This would require the zfcp erp,
but the erp thread is already blocked in the register call.

The fix is to make sure that the calls from the ERP thread to
the SCSI stack do not block the ERP thread. In detail:
1) Use a workqueue to avoid blocking of the scsi_scan_target calls.
2) When removing a unit make sure that no scsi_scan_target call is
   pending.
3) Replace scsi_flush_work with scsi_target_unblock. This avoids
   blocking and has the same result.

Christof Schmitt b03670e527 [SCSI] zfcp: Stop system after memory corruption
For each request that is sent to the FCP adapter, zfcp allocates
memory. Status information and data that is being read from the
device is written to this memory by the hardware. After that,
the hardware signals this via the response queue and zfcp
continues processing.

Now, if zfcp detects that there is a signal for an incoming
response from the hardware, but there is no outstanding request
for that request id, then some memory that can be in use anywhere
in the system has just been overwritten. This should never happen,
but if it does, stop the system with a panic.

Ursula Braun 0be4acec82 s390: fix Oops when unloading module netiucv
don't remove an entry from iucv_connection_list in netiucv_exit().
netiucv_free_netdevice is called anyway, which takes care of entry
removal.

Ursula Braun 1f8bdae9ef s390: free skbs in finite amount of time in qeth
Free sent skbs in some finite amount of time. Affected are
asynchronous queue of Hipersockets devices and the output
queues of all eth-devices respectively.

Ursula Braun a4c48a2691 s390: qeth driver connection hang
Frank Pavlic <fpavlic@de.ibm.com>

Connection hangs when using EDDP mode because sk_protocol is NULL
when skb has been copied via skb_copy. This results in dropping
packets.
Also keep MAC address after recovery of Virtual NICs so that
traffic can flow again and duplicate statements in
qeth_dev_set_route_store removed.
