when we use remap_file_pages() to remap a file, remap_file_pages always return
error. It is because btrfs didn't set VM_CAN_NONLINEAR for vma.

refs can be used with uninitialized data if btrfs_lookup_extent_info()
fails on the first pass through the loop. In the original code if that
happens then check_path_shared() probably returns 1, this patch
changes it to return 1 for safety.

Seems that when btrfs_fallocate was converted to use the new ENOSPC stuff we
dropped passing the mode to the function that actually does the preallocation.
This breaks anybody who wants to use FALLOC_FL_KEEP_SIZE. Thanks,

We cannot use the loop device which has been connected to a file in the btrf
The reproduce steps is following:
# dd if=/dev/zero of=vdev0 bs=1M count=1024
# losetup /dev/loop0 vdev0
# mkfs.btrfs /dev/loop0
...
failed to zero device start -5
The reason is that the btrfs don't implement either ->write_begin or ->write
the VFS API, so we fix it by setting ->write to do_sync_write().

gen_kill_estimator() / gen_new_estimator() is not always called with
RTNL held.
net/netfilter/xt_RATEEST.c is one user of these API that do not hold
RTNL, so random corruptions can occur between "tc" and "iptables".
Add a new fine grained lock instead of trying to use RTNL in netfilter.

Currently, the accelerated receive path for VLAN's will
drop packets if the real device is an inactive slave and
is not one of the special pkts tested for in
skb_bond_should_drop(). This behavior is different then
the non-accelerated path and for pkts over a bonded vlan.
For example,
vlanx -> bond0 -> ethx
will be dropped in the vlan path and not delivered to any
packet handlers at all. However,
bond0 -> vlanx -> ethx
and
bond0 -> ethx
will be delivered to handlers that match the exact dev,
because the VLAN path checks the real_dev which is not a
slave and netif_recv_skb() doesn't drop frames but only
delivers them to exact matches.
This patch adds a sk_buff flag which is used for tagging
skbs that would previously been dropped and allows the
skb to continue to skb_netif_recv(). Here we add
logic to check for the deliver_no_wcard flag and if it
is set only deliver to handlers that match exactly. This
makes both paths above consistent and gives pkt handlers
a way to identify skbs that come from inactive slaves.
Without this patch in some configurations skbs will be
delivered to handlers with exact matches and in others
be dropped out right in the vlan path.
I have tested the following 4 configurations in failover modes
and load balancing modes.
# bond0 -> ethx
# vlanx -> bond0 -> ethx
# bond0 -> vlanx -> ethx
# bond0 -> ethx

If we have enough memory to allocate a new cap release message, do so, so
that we can send a partial release message immediately. This keeps us from
making the MDS wait when the cap release it needs is in a partially full
release message.
If we fail because of ENOMEM, oh well, they'll just have to wait a bit
longer.

If we get an IMPORT that give us a cap, but we don't have the inode, queue
a release (and try to send it immediately) so that the MDS doesn't get
stuck waiting for us.

cb->atapi.cdb is an array of 16 u8 elements. The call too memset()
would set the first part of the sge array to zero as well. It's not
a packed struct.
This one has been around for five years. I found it with Smatch. I
think the reason no one has seen it before is because we normally call
sil24_fill_sg() and that overwrites sge with proper information?

This one adds support of a combined irq source for the whole matrix keypad.
This can be useful if all rows and columns of the keypad are e.g. connected
to a GPIO expander, which only has one interrupt line for all events on
every single GPIO.

* 'kvm-updates/2.6.35' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
KVM: read apic->irr with ioapic lock held

KVM: Fix order passed to iommu_unmap

KVM: powerpc: fix init/exit annotation
As it stands this check compares the number of pages to the page size.
This makes no sense and makes the fcntl fail in almost any sane case.
Fix it by checking if nr_pages is not zero (it can become zero only if
arg is too big and round_pipe_size() overflows).

I don't like the subtle multi-context code in bd_claim (ie. detects where it
has been called based on bd_claiming). It seems clearer to just require a new
function to finish a 2-part claim.
Also improve commentary in bd_start_claiming as to how it should
be used.
