Steps to reproduce:
i=0
ncases=100
mkfs.btrfs <disk>
mount <disk> <mnt>
btrfs quota enable <mnt>
btrfs qgroup create 2/1 <mnt>
while [ $i -le $ncases ]
do
btrfs qgroup create 1/$i <mnt>
btrfs qgroup assign 1/$i 2/1 <mnt>
i=$(($i+1))
done
btrfs quota disable <mnt>
umount <mnt>
btrfsck <mnt>
You can also use the commands:
btrfs-debug-tree <disk> | grep QGROUP
You will find there are still items existed.The reasons why this happens
is because the original code just checks slots[0]==0 and returns.
We try to fix it by deleting the leaf one by one.

Given a device with many channels capabilities the wiphy
information can still overflow even though its size in
3.9 was reduced to 3.8 levels. For new userspace and
kernel 3.10 we're going to implement a new "split dump"
protocol that can use multiple messages per wiphy.
For now though, add a workaround to be able to send more
information to userspace. Since generic netlink doesn't
have a way to set the minimum dump size globally, and we
wouldn't really want to set it globally anyway, increase
the size only when needed, as described in the comments.
As userspace might not be prepared for large buffers, we
can only use 4k.
Also increase the size for the get_wiphy command.

The SP805 driver is only used by the Spear machines, and uses

devices. For those devices do not use the extra software timer, but
directly program the time into the register. This will automatically be

Replace the existing STMP3xxx driver because it has enough drawbacks
that a rewrite is apropriate. The new driver is designed to use the
watchdog framework which makes it a lot smaller and avoids open coding
the watchdog API again. It also uses now an explicitly exported function
from the RTC driver to set up its registers (the old driver silently
reused the hopefully(!) already remapped RTC registers). Also, this
driver is mach independent, while the old one depends on a mach replaced
by another one a year ago. Since the user interface is still the
standard watchdog API, users don't need to adapt.

The ath79_wdt driver uses a fixed memory address
currently. Although this is working with each
currently supported SoCs, but this may change
in the future. Additionally, the driver includes
platform specific header files in order to be
able to get the memory base of the watchdog
device.
The patch adds a memory resource to the platform
device, and converts the driver to get the base
address of the watchdog device from that.

instead of zero
In case of SP5100 or SB7x0 chipsets, the sp5100_tco module writes zero to
reserved bits. The module, however, shouldn't depend on specific default
value, and should perform a read-merge-write operation for the reserved
bits.
This patch makes the sp5100_tco module perform a read-merge-write operation
on all the chipset (sp5100, sb7x0, sb8x0 or later).

reserved bits
In case of SB800 or later chipset and re-programming MMIO address(*),
sp5100_tco module may read incorrect value of reserved bit, because the module
reads a value from an incorrect I/O address. However, this bug doesn't cause
a problem, because when re-programming MMIO address, by chance the module
writes zero (this is BIOS's default value) to the low three bits of register.
* In most cases, PC with SB8x0 or later chipset doesn't need to re-programming
MMIO address, because such PC can enable AcpiMmio and can use 0xfed80b00 for
watchdog register base address.
This patch fixes this bug.

When the system is under memory pressure, ext4_es_srhink() will get
called very often. So optimize returning the number of items in the
file system's extent status cache by keeping a per-filesystem count,
instead of calculating it each time by scanning all of the inodes in
the extent status cache.
Also rename the slab used for the extent status cache to be
"ext4_extent_status" so it's obviousl the slab in question is created
by ext4.
