Subject: [PATCH] splice: introduce FMODE_SPLICE_READ and FMODE_SPLICE_WRITE
Introduce FMODE_SPLICE_READ and FMODE_SPLICE_WRITE. These modes check
whether it is legal to read or write a file using splice. Both get
automatically set on regular files and are not checked when a 'struct
fileoperations' includes the splice_{read,write} methods.

Subject: [PATCH] BACKPORT: block: add blk_rq_set_block_pc()
With the optimizations around not clearing the full request at alloc
time, we are leaving some of the needed init for REQ_TYPE_BLOCK_PC
up to the user allocating the request.
Add a blk_rq_set_block_pc() that sets the command type to
REQ_TYPE_BLOCK_PC, and properly initializes the members associated
with this type of request. Update callers to use this function instead
of manipulating rq->cmd_type directly.
Includes fixes from Christoph Hellwig <hch@lst.de> for my half-assed
attempt.

From 2c5b488b49d92c02ac28f45e68f366c6a51a8949 Mon Sep 17 00:00:00 2001
From: Douglas Gilbert <dgilbert@interlog.com>
Date: Tue, 03 Jun 2014 13:18:18 -0400
Subject: [PATCH] BACKPORT: sg: relax 16 byte cdb restriction
- remove the 16 byte CDB (SCSI command) length limit from the sg driver
by handling longer CDBs the same way as the bsg driver. Remove comment
from sg.h public interface about the cmd_len field being limited to 16
bytes.
- remove some dead code caused by this change
- cleanup comment block at the top of sg.h, fix urls

-Original driver (sg.h):
-* Copyright (C) 1992 Lawrence Foard
-Version 2 and 3 extensions to driver:
-* Copyright (C) 1998 - 2006 Douglas Gilbert
-
- Version: 3.5.34 (20060920)
- This version is for 2.6 series kernels.
-
- For a full changelog see http://www.torque.net/sg
-
-Map of SG verions to the Linux kernels in which they appear:
- ---------- ----------------------------------
- original all kernels < 2.2.6
- 2.1.40 2.2.20
- 3.0.x optional version 3 sg driver for 2.2 series
- 3.1.17++ 2.4.0++
- 3.5.30++ 2.6.0++
-
-Major new features in SG 3.x driver (cf SG 2.x drivers)
- - SG_IO ioctl() combines function if write() and read()
- - new interface (sg_io_hdr_t) but still supports old interface
- - scatter/gather in user space, direct IO, and mmap supported
-
- The normal action of this driver is to use the adapter (HBA) driver to DMA
- data into kernel buffers and then use the CPU to copy the data into the
- user space (vice versa for writes). That is called "indirect" IO due to
- the double handling of data. There are two methods offered to remove the
- redundant copy: 1) direct IO and 2) using the mmap() system call to map
- the reserve buffer (this driver has one reserve buffer per fd) into the
- user space. Both have their advantages.
- In terms of absolute speed mmap() is faster. If speed is not a concern,
- indirect IO should be fine. Read the documentation for more information.
-
- ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
- 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
- That attribute is 0 by default. **
-
- Historical note: this SCSI pass-through driver has been known as "sg" for
- a decade. In broader kernel discussions "sg" is used to refer to scatter
- gather techniques. The context should clarify which "sg" is referred to.
-
- Documentation
- =============
- A web site for the SG device driver can be found at:
- http://www.torque.net/sg [alternatively check the MAINTAINERS file]
- The documentation for the sg version 3 driver can be found at:
- http://www.torque.net/sg/p/sg_v3_ho.html
- This is a rendering from DocBook source [change the extension to "sgml"
- or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
- The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
- For more information see http://www.torque.net/sg/sg_io.html
-
- The older, version 2 documents discuss the original sg interface in detail:
- http://www.torque.net/sg/p/scsi-generic.txt
- http://www.torque.net/sg/p/scsi-generic_long.txt
- Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
-
- Utility and test programs are available at the sg web site. They are
- packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
- (for the lk 2.2 series).

The user can control the size of the next command passed along, but the

Subject: [PATCH] BACKPORT: block: add blk_rq_set_block_pc()
With the optimizations around not clearing the full request at alloc
time, we are leaving some of the needed init for REQ_TYPE_BLOCK_PC
up to the user allocating the request.
Add a blk_rq_set_block_pc() that sets the command type to
REQ_TYPE_BLOCK_PC, and properly initializes the members associated
with this type of request. Update callers to use this function instead
of manipulating rq->cmd_type directly.
Includes fixes from Christoph Hellwig <hch@lst.de> for my half-assed
attempt.

From 8093bf02878aa659cfcf8cbfc272b2ad45eef24f Mon Sep 17 00:00:00 2001
From: Douglas Gilbert <dgilbert@interlog.com>
Date: Tue, 03 Jun 2014 13:18:18 -0400
Subject: [PATCH] BACKPORT: sg: relax 16 byte cdb restriction
- remove the 16 byte CDB (SCSI command) length limit from the sg driver
by handling longer CDBs the same way as the bsg driver. Remove comment
from sg.h public interface about the cmd_len field being limited to 16
bytes.
- remove some dead code caused by this change
- cleanup comment block at the top of sg.h, fix urls

-Original driver (sg.h):
-* Copyright (C) 1992 Lawrence Foard
-Version 2 and 3 extensions to driver:
-* Copyright (C) 1998 - 2006 Douglas Gilbert
-
- Version: 3.5.34 (20060920)
- This version is for 2.6 series kernels.
-
- For a full changelog see http://www.torque.net/sg
-
-Map of SG verions to the Linux kernels in which they appear:
- ---------- ----------------------------------
- original all kernels < 2.2.6
- 2.1.40 2.2.20
- 3.0.x optional version 3 sg driver for 2.2 series
- 3.1.17++ 2.4.0++
- 3.5.30++ 2.6.0++
-
-Major new features in SG 3.x driver (cf SG 2.x drivers)
- - SG_IO ioctl() combines function if write() and read()
- - new interface (sg_io_hdr_t) but still supports old interface
- - scatter/gather in user space, direct IO, and mmap supported
-
- The normal action of this driver is to use the adapter (HBA) driver to DMA
- data into kernel buffers and then use the CPU to copy the data into the
- user space (vice versa for writes). That is called "indirect" IO due to
- the double handling of data. There are two methods offered to remove the
- redundant copy: 1) direct IO and 2) using the mmap() system call to map
- the reserve buffer (this driver has one reserve buffer per fd) into the
- user space. Both have their advantages.
- In terms of absolute speed mmap() is faster. If speed is not a concern,
- indirect IO should be fine. Read the documentation for more information.
-
- ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
- 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
- That attribute is 0 by default. **
-
- Historical note: this SCSI pass-through driver has been known as "sg" for
- a decade. In broader kernel discussions "sg" is used to refer to scatter
- gather techniques. The context should clarify which "sg" is referred to.
-
- Documentation
- =============
- A web site for the SG device driver can be found at:
- http://www.torque.net/sg [alternatively check the MAINTAINERS file]
- The documentation for the sg version 3 driver can be found at:
- http://www.torque.net/sg/p/sg_v3_ho.html
- This is a rendering from DocBook source [change the extension to "sgml"
- or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
- The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
- For more information see http://www.torque.net/sg/sg_io.html
-
- The older, version 2 documents discuss the original sg interface in detail:
- http://www.torque.net/sg/p/scsi-generic.txt
- http://www.torque.net/sg/p/scsi-generic_long.txt
- Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
-
- Utility and test programs are available at the sg web site. They are
- packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
- (for the lk 2.2 series).

Subject: [PATCH] scsi: sg: check length passed to SG_NEXT_CMD_LEN
The user can control the size of the next command passed along, but the
value passed to the ioctl isn't checked against the usable max command
size.

Subject: [PATCH] ASoC: msm: qdsp6v2: validate audio client in callback
In case of single stream multiple device(SSMD) use-case audio session is
freed on first EOS. There are some chance to crash when 2nd EOS event is
reached with some delay. This make sure return properly if audio client
is not valid.

Subject: [PATCH] ASoC: msm: qdsp6v2: check audio client pointer before accessing
In the registered callback for q6asm, we are checking if
the audio client pointer is valid and also, dereferencing it
to get the session ID even though it could be invalid or expired.
Return and exit immediately if the audio client pointer is
invalid.
