Andreas Herrmann 65a8d4e1a3 [SCSI] zfcp: fix: reopen port only if link-test fails
From: Maxim Shchetynin <maxim@de.ibm.com>

Reopen a remote port only if the link-test fails. This avoids that a
port is unnecessarily reopened.

Andreas Herrmann 22753fa514 [SCSI] zfcp: fix: allow more time for adapter initialization
From: Maxim Shchetynin <maxim@de.ibm.com>

Extend the time for adapter initialization: In case of protocol
status HOST_CONNECTION_INITIALIZING for the exchange config data
command do a first retry in 1 second, then double the sleep time for
each following retry until recovery exceeds 2 minutes. The old
behaviour of allowing 6 retries with .5 seconds delay between retries
was insufficient and qdio queues were shut down too erarly.

Fixes the handling of failed requests for GID_PN nameserver command:
Set ZFCP_STATUS_PORT_INVALID_WWPN only if indicated by response
payload for GID_PN nameserver command and not if fsf request fails.

Horst Hummel 59afda786a [PATCH] s390: dasd set online failure
dasd driver changes:
 - The feature check in dasd_generic_online returns an error if
   the devmap entry for the device is not yet available. Check
   for the feature after the device has been created.
 - Do symmetric registration/deregistration of cdev->handler.

[patch 10/10] s390: qeth bug fixes.

From: Frank Pavlic <pavlic@de.ibm.com>

qeth network driver related changes:
 - due to OSA hardware changes in TCP Segmentation Offload
   support we are able now to pack TSO packets too.
   This fits perfectly in design of qeth buffer handling and
   sending data respectively.
 - remove skb_realloc_headroom from the sending path since
   hard_header_len value provides enough headroom now.
 - device recovery behaviour improvement
 - bug fixed in Enhanced Device Driver Packing functionality

[patch 7/10] s390: qeth bug fixes.

From: Frank Pavlic <pavlic@de.ibm.com>

qeth network driver changes:
 - Removed redundant code, use the same qeth_fill_buffer_frag
   for TSO path either
 - Using skb->frags solely is not correct since skb->data still
   points to the beginning of the whole data, even when it is
   a small portion we have to fill the qdio buffer with it.

Frank Pavlic b5f9d55b64 [PATCH] s390: set online race in the lcs driver
[patch 3/10] s390: set online race in the lcs driver.

From: Michael Holzheu <holzheu@de.ibm.com>

There is a race between lcs_stopcard() and lcs_open_device() which
can lead to the error 'lcs: Error in starting channel, rc=-16'.
lcs_open_device() is invoked when 'ifconfig up' is called due to a
hotplug event, which is caused by register_netdev(). In parallel
lcs_stopcard() is executed. Both functions are sending lcs commands.
The second invocation fails with -EBUSY (-16) as return value.
Move invocation of register_netdev() after invocation of lcs_stopcard
to avoid the race.

Horst Hummel ec5883abeb [PATCH] s390: don't pad cdl blocks for write requests
The first blocks on a cdl formatted dasd device are smaller than the blocksize
of the device.  Read requests are padded with a 'e5' pattern.  Write requests
should not pad the (user) buffer with 'e5' because a write request is not
allowed to modify the buffer.

Stefan Weinhuber 6ed93c827e [PATCH] s390: enable write barriers in the dasd driver
The DASD device driver never reorders the I/O requests and relies on the
hardware to write all data to nonvolatile storage before signaling a
successful write.  Hence, the only thing we have to do to support write
barriers is to set the queue ordered flag.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
