[PATCH] ext4: fix freeze deadlock under IO
Commit 6b0310fbf087ad6 caused a regression resulting in deadlocks
when freezing a filesystem which had active IO; the vfs_check_frozen
level (SB_FREEZE_WRITE) did not let the freeze-related IO syncing
through. Duh.
Changing the test to FREEZE_TRANS should let the normal freeze
syncing get through the fs, but still block any transactions from
starting once the fs is completely frozen.
I tested this by running fsstress in the background while periodically
snapshotting the fs and running fsck on the result. I ran into
occasional deadlocks, but different ones. I think this is a
fine fix for the problem at hand, and the other deadlocky things
will need more investigation.

Some devices (like the nuforce udac) spew this quite a lot.
This patch kinda sucks, but it'll shut things up for now.
Probably not an upstream candidate. I suspect the answer would be
"don't turn SND_DEBUG then"

commit 611225f5e7f9d11c4b119fac224f1bd6903b0150
Author: Jarod Wilson <jarod@redhat.com>
Date: Sun Mar 7 17:55:43 2010 -0300
V4L/DVB: dvb: add support for kworld 340u and ub435-q to em28xx-dvb
This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.
The stick has been tested succesfully with both VSB_8 and QAM_256 signals.
Its using lgdt3304 support added to the lgdt3305 driver by a prior patch,
rather than the current lgdt3304 driver, as its severely lacking in
functionality by comparison (see said patch for details).

From linville@tuxdriver.com Thu Jul 15 15:40:22 2010
From: "John W. Linville" <linville@tuxdriver.com>
Subject: [RFC] wireless: only use alpha2 regulatory information from country IE
Date: Thu, 15 Jul 2010 15:06:47 -0400
The meaning and/or usage of the country IE is somewhat poorly defined.
In practice, this means that regulatory rulesets in a country IE are
often incomplete and might be untrustworthy. This removes the code
associated with interpreting those rulesets while preserving respect
for country "alpha2" codes also contained in the country IE.
Signed-off-by: John W. Linville <linville@tuxdriver.com>
---
This patch is compile-tested only! Please feel free to suggest that
I have left something out or missed some nuance of our regulatory
enforcement code...

From: Matthew Garrett <mjg@redhat.com>
Subject: ACPI: Disable ASPM if the platform won't provide _OSC control for PCIe
ACPI: Disable ASPM if the platform won't provide _OSC control for PCIe
The PCI SIG documentation for the _OSC OS/firmware handshaking interface
states:
"If the _OSC control method is absent from the scope of a host bridge
device, then the operating system must not enable or attempt to use any
features defined in this section for the hierarchy originated by the host
bridge."
The obvious interpretation of this is that the OS should not attempt to use
PCIe hotplug, PME or AER - however, the specification also notes that an
_OSC method is *required* for PCIe hierarchies, and experimental validation
with An Alternative OS indicates that it doesn't use any PCIe functionality
if the _OSC method is missing. That arguably means we shouldn't be using
MSI or extended config space, but right now our problems seem to be limited
to vendors being surprised when ASPM gets enabled on machines when other
OSs refuse to do so. So, for now, let's just disable ASPM if the _OSC
method doesn't exist or refuses to hand over PCIe capability control.

Subject: PCI: Don't enable aspm before drivers have had a chance to veto it
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fjbarnes%2Fpci-2.6.git;a=commitdiff_plain;h=8f0b08c29f1df91315e48adce04462eb23671099
PCI: Don't enable aspm before drivers have had a chance to veto it
The aspm code will currently set the configured aspm policy before drivers
have had an opportunity to indicate that their hardware doesn't support it.
Unfortunately, putting some hardware in L0 or L1 can result in the hardware
no longer responding to any requests, even after aspm is disabled. It makes
more sense to leave aspm policy at the BIOS defaults at initial setup time,
reconfiguring it after pci_enable_device() is called. This allows the
driver to blacklist individual devices beforehand.

Subject: utrace: remove use of kref_set
Unfortunatey db1afffa which removed kref_set did not anticipate
anyone would actually like to use a kref which starts with a refcnt
above 1. Replace kref_set in utrace with a kref_init + kref_get to
immediately bump the reference count.
