Hello,
This patch series reworks the flip-work framework to make it safe when
calling drm_flip_work_queue from atomic contexts.
The 2nd patch of this series is optional, as it only reworks
drm_flip_work_init prototype to remove unneeded size argument and
return code (this function cannot fail any
Now that we're using lists instead of kfifo to store drm flip-work tasks
we do not need the size parameter passed to drm_flip_work_init function
anymore.
Moreover this function cannot fail anymore, we can thus remove the return
code.
Modify drm_flip_work_init users to take account of these changes

libata-eh.c should handle AMNF error condition (error byte bit 0, usually
code 0x01) in libata-eh.c along with UNC as a media error so SCSI stack
can handle it properly (translation code 0x01 is already present in
libata-scsi.c) but was never passed down due to lack of handling in EH.

PowerPC is the only architecture that makes use of hook
arch_msi_check_device() and does perform some checks to

However, there are no reasons why those checks could not

Hello,
This patch series reworks the flip-work framework to make it safe when
calling drm_flip_work_queue from atomic contexts.
The 2nd patch of this series is optional, as it only reworks
drm_flip_work_init prototype to remove unneeded size argument and
return code (this function cannot fail any
Make use of lists instead of kfifo in order to dynamically allocate
task entry when someone require some delayed work, and thus preventing
drm_flip_work_queue from directly calling func instead of queuing this
call.
This allow drm_flip_work_queue to be safely called even within irq
handlers.
Add n
Now that we're using lists instead of kfifo to store drm flip-work tasks
we do not need the size parameter passed to drm_flip_work_init function
anymore.
Moreover this function cannot fail anymore, we can thus remove the return
code.
Modify drm_flip_work_init users to take account of these changes

Make use of the pi_() helpers to mark the strings printed during
initialization for automatic release. Do so for the strings used in
command line parsing as well, by using the __init_str() macro.
The debug messages have been converted to printk_init(KERN_DEBUG ...)
instead of pi_debug(...), though
The __init_str() / __exit_str() annotations create pseudo symbols.
Ignore them, they have no value for us.

This is v2 of the patch series initially posted here:
https://lkml.org/lkml/2014/6/22/149
I've integrated Joe's idea of also providing printk_init() /
printk_exit() wrappers for code that cannot (or doesn't want to) be
converted to the pi_*() / pe_*() wrappers.
Patches 4 and 5 are cleanup patc
The memory used for functions marked with __init will be released after
initialization, albeit static data referenced by such code will not, if
not explicitly marked this way, too. This is especially true for format
strings used in messages printed by such code. Those are not marked and
therefore w
early_printk() and panic() expect a format string as first argument.
Change early_panic() to pass on the message as string instead of a
format string.

In this patch set I have fixed a few bugs and implemented some enhancements.

Correctly set SRB flags for all valid I/O directions. Some IHV drivers on the
Windows host require this. The host validates the command and SRB flags
prior to passing the command down to native driver stack.

On some Windows hosts on FC SANs, TEST_UNIT_READY can return SRB_STATUS_ERROR.
Correctly handle this. Note that there is sufficient sense information to
support scsi error handling even in this case.

Hyper-V hosts can support multiple targets and multiple channels and larger
number of
LUNs per target. Update the code to reflect this. With this patch we can

Going forward it is possible that some of the commands that are not currently
implemented will be implemented on future Windows hosts. Even if they are not
implemented, we are told the host will corrrectly handle unsupported
commands (by returning appropriate return code and sense information).

On Azure, we have seen instances of unbounded I/O latencies. To deal with
this issue, implement handler that can reset the timeout. Note that the
host gaurantees that it will respond to each command that has been issued.

Based on the negotiated VMBUS protocol version, we adjust the size of the
storage
protocol messages. The two sizes we currently handle are pre-win8 and post-win8.
In WS2012 R2, we are negotiating higher VMBUS protocol version than the win8
version. Make adjustments to correctly handle this.
