GFS2: Extend umount wait coverage to full glock lifetime
GFS2: Wait for unlock completion on umount

Although all glocks are, by the time of the umount glock wait,
scheduled for demotion, some of them haven't made it far
enough through the process for the original set of waiting
code to wait for them.
This extends the ref count to the whole glock lifetime in order
to ensure that the waiting does catch all glocks. It does make
it a bit more invasive, but it seems the only sensible solution
at the moment.

This patch adds a wait on umount between the point at which we
dispose of all glocks and the point at which we unmount the
lock protocol. This ensures that we've received all the replies
to our unlock requests before we stop the locking.

Commit 859ddf09743a8cc680af33f7259ccd0fd36bfe9d tried to fix
misallocation bug but broke full bit marking by not clearing
pa[idp->layers] and also is causing X failures due to lookup failure
in drm code. The cause of the latter hasn't been found yet. Revert
the fix for now.

Getting it is not used, let's drop support for notifications about
(un)registered events from connector.
Another option was to check credentials on receiving, but we can always
restore it without bugs if needed, but genetlink has a wider code base
and none complained, that userspace can not get notification when some
other clients were (un)registered.
Kudos for Sebastian Krahmer <krahmer@suse.de>, who found a bug in the
code.

In commit 2da31939a42f7a676a0bc5155d6a0a39ed8451f2, support
for Bluetooth hid_output_raw_report was added, but it pushes
the data to the interrupt channel instead of the contol one.
This patch makes hid_output_raw_report use the control channel
instead. Using the interrupt channel was a mistake.

Commit ac019360fe3 changed the irq handler logic to BUG_ON rather than
returning IRQ_NONE when the incoming argument is invalid. While this
works in most cases, it doesn't work when the IRQ is shared with other
devices (or when DEBUG_SHIRQ is enabled).
So revert the previous change and replace the warning message with a
comment explaining that we want this behavior.

Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down
initially for drivers that update link state") changed the initial link
state in cdc_ether and other drivers based on the understanding that the
devices they support generate link change interrupts. However, this is
optional in the CDC Ethernet protocol, and two users have reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
for their devices remains down. Therefore, revert the change in
cdc_ether.

ath9k: Enable Fractional N mode
changed the hw attach code to fix up initialization values only for
dual band devices, however the commit message did not give a reason as
to why this would be useful or necessary.
According to tests by Jorge Boncompte, this breaks at least some
2GHz-only cards, so the code should be changed back to the
unconditional INI fixup.

There are a few station addresses that are
char *, instead of the normal u8 *; gcc
gives pointer signedness warnings for some
of those, so use u8 * consistently.

When cleaning up beacon buffers and slots, ath9k currently checks if
sc->ah->opmode is set to a beacon related mode before cleaning up
buffers.
An unfortunate ordering of interface up/down commands can lead to
sc->ah->opmode being set to monitor mode, while there are AP interfaces
present on the same wiphy.
Always cleaning up beacon buffers if present fixes this issue.

netdev_open() will return without cleaning up net device or hardware state
if firmware loading fails. This results in a BUG() on a second attempt to
bring the interface up, reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even
worse effects if the driver is removed afterwards.
Call netdev_close() to clean up on failure.

The commit 0b5ccb2(title:ipv6: reassembly: use seperate reassembly queues for
conntrack and local delivery) has broken the saddr&&daddr member of
nf_ct_frag6_queue when creating new queue. And then hash value
generated by nf_hashfn() was not equal with that generated by fq_find().
So, a new received fragment can't be inserted to right queue.
The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure.

This is the counterpart to cba767175becadc5c4016cceb7bfdd2c7fe722f4
("pktcdvd: remove broken dev_t export of class devices"). Device is not
registered using dev_t, so it should not be destroyed using device_destroy
which looks up the device by dev_t. This will fail and adding the device
again will fail with the "duplicate name" error. This is fixed using
device_unregister instead of device_destroy.

Newly added memory can not be accessed via /dev/mem, because we do not
update the variables high_memory, max_pfn and max_low_pfn.
Add a function update_end_of_memory_vars() to update these variables for
64-bit kernels.

The probe function passes a pointer to a struct fb_info to
platform_set_drvdata(), so don't interpret the return value of
platform_get_drvdata() as a pointer to struct imxfb_info.
The original imxfb_info *fbi backlight_power was NULL but in imxfb_suspend
it was 4 resulting in an oops as imxfb_suspend calls
imxfb_disable_controller(fbi) which in turn has
if (fbi->backlight_power)
fbi->backlight_power(0);

In cgroup_create(), if alloc_css_id() returns failure, the errno is not
propagated to userspace, so mkdir will fail silently.
To trigger this bug, we mount blkio (or memory subsystem), and create more
then 65534 cgroups. (The number of cgroups is limited to 65535 if a
subsystem has use_id == 1)
# mount -t cgroup -o blkio xxx /mnt
# for ((i = 0; i < 65534; i++)); do mkdir /mnt/$i; done
# mkdir /mnt/65534
(should return ENOSPC)

NaN
This NaN is from:
main::(./m.pl:176): my $decodestart = Math::BigInt->from_hex("0x$target") - Math::BigInt->from_hex("0x$func_offset");
DB<2> p $func_offset
0x175
There is already a "0x" in $func_offset, another 0x makes it a NaN.
The $func_offset is from line:
if ($line =~ /RIP: 0010:\[\<[0-9a-f]+\>\] \[\<[0-9a-f]+\>\] ([a-zA-Z0-9\_]+)\+(0x[0-9a-f]+)\/0x[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}
I make a patch to change "(0x[0-9a-f]+)\/0x[a-f0-9]/)" to "0x([0-9a-f]+)\/0x[a-f0-9]/)".

When git has been set to always use color in .gitconfig then I get the
warning message
Bad divisor in main::vcs_assign: 0
This is caused by vcs_file_signoffs not matching any commits due to the
pattern not understand the colour codes. Fix this by telling git log to
never use colour.
