dev-loss-tmo/terminate_rport_io callbacks.
Commit f78badb1ae07e7f8b835ab2ea0b456ed3fc4caf4 ([SCSI] fc
transport: pre-emptively terminate i/o upon dev_loss_tmo timeout)
changed the callback semantics of dev_loss_tmo and
terminate_rport_io such that repeated calls could be made. This
could result in the the driver using stale (NULLed-out, in
dev_loss_tmo) data from the rport. Correct this by addint a
simple check to ensure a valid fcport is attached.

Jeremy Higdon noted
(http://marc.info/?l=linux-scsi&m=123262143131788&w=2) that the
rework done in commit e315cd28b9ef0d7b71e462ac16e18dbaa2f5adfe
was not setting the proper consistent and streaming DMA masks
prior to memory allocations. Correct this and remove the
unnecessary prototype.

When clearing the flash device's SR, the comment is incorrect...
clearing the SR is 2 steps:
1. the SR protect bit is 1, so the first write zero clears only
that bit,
2. the SR protect bit is now 0, so the next write zero clears the
remaining bits.
The sector erase debug print more correctly identifies that the erase failed.

Pre-ISP81XX parts (including ISP24xx and ISP25xx) could contain a
firmware image within a segment of flash, driver would fallback
to loading this firmware if the request-firmware interface failed
(userspace .bin file). Moving forward, all ISP81XX parts will
ship with a suggested-to-be-used firmware image within flash
which all driver should first attempt to load. If the flash
firmware load fails, the driver will then fallback to loading
firmware via the request-firmware interface (ql8100_fw.bin).

Original code would incorrectly bypass serialization if the DPC
thread were performing a big-hammer operation (ISP abort). This
short circuit, though rare, would subsequently stomp on a

qla4xxx does not check the I_T nexus values correctly
so it ends up creating one session to the target. If
a portal should disappear or they should be reported
in different order the driver will think it is already
logged in when it could now be speaking to a different
target portal or accessing it through a different
initiator port (iscsi initiator port is not tied to
hardware and is just the initiator name plus isid
so you could end up with multiple ports through one
host).
This patch has the driver check the iscsi scsi port
values when matching sessions (we do not check
the initiator name because that is static). It results
in a portal from each target portal group getting
logged into instead of just one per target. In the future
the firmware should hopefully send us notification of other
sessions that are created to other portals within the
same tpgt and the sessions should have different isids.

I am not sure what happened. It looks like we have always leaked
the q->queue that is allocated from the kfifo_init call. nab finally
noticed that we were leaking and this patch fixes it by adding a
kfree call to iscsi_pool_free. kfifo_free is not used per kfifo_init's
instructions to use kfree.

A pointer to wm8400_regulator_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

The current work request posting code writes the LSO segment before
writing any data segments. This leaves a window where the LSO segment
overwrites the stamping in one cacheline that the HCA prefetches
before the rest of the cacheline is filled with the correct data
segments. When the HCA processes this work request, a local
protection error may result.
Fix this by saving the LSO header size field off and writing it only
after all data segments are written. This fix is a cleaned-up version
of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1383>.

Btrfs: fix ioctl arg size (userland incompatible change!)
Btrfs: Clear the device->running_pending flag before bailing on congestion
|
|
The structure used to send device in btrfs ioctl calls was not
properly aligned, and so 32 bit ioctls would not work properly on
64 bit kernels.
We could fix this with compat ioctls, but we're just one byte away
and it doesn't make sense at this stage to carry about the compat ioctls
forever at this stage in the project.
This patch brings the ioctl arg up to an evenly aligned 4k.

Btrfs maintains a queue of async bio submissions so the checksumming
threads don't have to wait on get_request_wait. In order to avoid
extra wakeups, this code has a running_pending flag that is used
to tell new submissions they don't need to wake the thread.
When the threads notice congestion on a single device, they
may decide to requeue the job and move on to other devices. This
makes sure the running_pending flag is cleared before the
job is requeued.
It should help avoid IO stalls by making sure the task is woken up
when new submissions come in.

This reverts commit 98e6e286d7b01deb7453b717aa38ebb69d6cefc0, as Yinghai
Lu reports that it breaks kexec with at least the e1000 and e1000e
drivers. The reason is that the shutdown sequence puts the hardware
into D3 sleep, and the commit causes us to claim that it then is in D0
(running) state just because we don't understand the PM capabilities.
Which then later makes "pci_set_power_state()" not do anything, and the
device never wakes up properly and just returns 0xff to everything.
