Try to reduce number of possible fn_sernum mutation by constraining them
to their namespace.
Also remove rt_genid which I forgot to remove in 705f1c869d577c ("ipv6:
remove rt6i_genid").

When Tx VLAN offloading is disabled frames with size ~ MTU are not
transmitted as the driver does not account 4 bytes of VLAN header added
by stack. It should use VLAN_ETH_HLEN instead of ETH_HLEN.
The second problem is with newer BNA chips (BNA 1860). These chips filter
out any VLAN tagged frames in Tx path. This is a problem when Tx VLAN
offloading is disabled and frames are tagged by stack. Older chips like
1010/1020 are not affected as they probably don't do such filtering.

With the introduction of the new keyboard backlight
implementation, the *_timeout_store function is
broken, as it only supports the first kbd_type.
This patch adapts such function for the new kbd_type,
as well as converts from using sscanf to kstrtoint.

This patch introduces a very limited functionality for atomic write support.
In order to support atomic write, this patch adds two ioctls:
o F2FS_IOC_START_ATOMIC_WRITE
o F2FS_IOC_COMMIT_ATOMIC_WRITE
The database engine should be aware of the following sequence.
1. open
-> ioctl(F2FS_IOC_START_ATOMIC_WRITE);
2. writes
: all the written data will be treated as atomic pages.
3. commit
-> ioctl(F2FS_IOC_COMMIT_ATOMIC_WRITE);
: this flushes all the data blocks to the disk, which will be shown all or
nothing by f2fs recovery procedure.
4. repeat to #2.
The IO pattens should be:
,- START_ATOMIC_WRITE ,- COMMIT_ATOMIC_WRITE
CP | D D D D D D | FSYNC | D D D D | FSYNC ...
`- COMMIT_ATOMIC_WRITE

John Fastabend says:
====================
net sched rcu updates
This fixes the use of tcf_proto from RCU callbacks it requires
moving the unbind calls out of the callbacks and removing the
tcf_proto argument from the tcf_em_tree_destroy().
This is a rework of two previous series and addresses comments
from Cong. And should apply against latest net-next.
The previous series links below for reference:
(1/2) net: sched: do not use tcf_proto 'tp' argument from call_rcu
http://patchwork.ozlabs.org/patch/396149/
(2/2) net: sched: replace ematch calls to use struct net
http://patchwork.ozlabs.org/patch/396150/

Using the tcf_proto pointer 'tp' from inside the classifiers callback
is not valid because it may have been cleaned up by another call_rcu
occuring on another CPU.
'tp' is currently being used by tcf_unbind_filter() in this patch we
move instances of tcf_unbind_filter outside of the call_rcu() context.
This is safe to do because any running schedulers will either read the
valid class field or it will be zeroed.
And all schedulers today when the class is 0 do a lookup using the
same call used by the tcf_exts_bind(). So even if we have a running
classifier hit the null class pointer it will do a lookup and get
to the same result. This is particularly fragile at the moment because
the only way to verify this is to audit the schedulers call sites.

This removes the tcf_proto argument from the ematch code paths that
only need it to reference the net namespace. This allows simplifying
qdisc code paths especially when we need to tear down the ematch
from an RCU callback. In this case we can not guarentee that the
tcf_proto structure is still valid.

Some TSO engines might have a too heavy setup cost, that impacts
performance on hosts sending small bursts (2 MSS per packet).
This patch adds a device gso_min_segs, allowing drivers to set
a minimum segment size for TSO packets, according to the NIC
performance.
Tested on a mlx4 NIC, this allows to get a ~110% increase of
throughput when sending 2 MSS per packet.

In case we find a general query with non-zero number of sources, we
are dropping the skb as it's malformed.
RFC3376, section 4.1.8. Number of Sources (N):
This number is zero in a General Query or a Group-Specific Query,
and non-zero in a Group-and-Source-Specific Query.
Therefore, reflect that by using kfree_skb() instead of consume_skb().

Earlier change to use usable slave array for TLB mode had an additional
performance advantage. So extending the same logic to all other modes
that use xmit-hash for slave selection (viz 802.3AD, and XOR modes).
Also consolidating this with the earlier TLB change.
The main idea is to build the usable slaves array in the control path
and use that array for slave selection during xmit operation.
Measured performance in a setup with a bond of 4x1G NICs with 200
instances of netperf for the modes involved (3ad, xor, tlb)

The NT flag doesn't do anything in long mode other than causing IRET
to #GP. Oddly, CPL3 code can still set NT using popf.
Entry via hardware or software interrupt clears NT automatically, so
the only relevant entries are fast syscalls.
If user code causes kernel code to run with NT set, then there's at
least some (small) chance that it could cause trouble. For example,
user code could cause a call to EFI code with NT set, and who knows
what would happen? Apparently some games on Wine sometimes do
this (!), and, if an IRET return happens, they will segfault. That
segfault cannot be handled, because signal delivery fails, too.
This patch programs the CPU to clear NT on entry via SYSCALL (both
32-bit and 64-bit, by my reading of the AMD APM), and it clears NT
in software on entry via SYSENTER.
To save a few cycles, this borrows a trick from Jan Beulich in Xen:
it checks whether NT is set before trying to clear it. As a result,
it seems to have very little effect on SYSENTER performance on my
machine.
There's another minor bug fix in here: it looks like the CFI
annotations were wrong if CONFIG_AUDITSYSCALL=n.
Testers beware: on Xen, SYSENTER with NT set turns into a GPF.
I haven't touched anything on 32-bit kernels.
The syscall mask change comes from a variant of this patch by Anish
Bhatt.
Note to stable maintainers: there is no known security issue here.
A misguided program can set NT and cause the kernel to try and fail
to deliver SIGSEGV, crashing the program. This patch fixes Far Cry

Split interrupt service routine into hardware context handler
and threaded context handler. That allows to protect ports with
individual locks rather than with a single host-wide lock and
move port interrupts handling out of the hardware interrupt
context.
Testing was done by transferring 8GB on two hard drives in
parallel using command 'dd if=/dev/sd{a,b} of=/dev/null'. With
lock_stat statistics I measured access times to ata_host::lock
spinlock (since interrupt handler code is fully embraced with
this lock). The average lock's holdtime decreased eight times
while average waittime decreased two times.
Both before and after the change the transfer time is the same,
while 'perf record -e cycles:k ...' shows 1%-4% CPU time spent
in ahci_single_irq_intr() routine before the update and not even
sampled/shown ahci_single_irq_intr() after the update.

As described in AHCI v1.0 specification chapter 10.6.2.2
"Multiple MSI Based Messages" generation of interrupts
is not controlled through the HOST_IRQ_STAT register.
Considering MMIO access is expensive remove unnecessary
reading and writing of HOST_IRQ_STAT register.
Further, serializing access to the host data is no longer
needed and the interrupt service routine can avoid competing
on the host lock.

security label.
[BUG]
Originally when mount btrfs with "-o subvol=" mount option, btrfs will
lose all security lable.
And if the btrfs fs is mounted somewhere else, due to the lost of
security lable, SELinux will refuse to mount since the same super block
is being mounted using different security lable.
[REPRODUCER]
With SELinux enabled:
#mkfs -t btrfs /dev/sda5
#mount -o context=system_u:object_r:nfs_t:s0 /dev/sda5 /mnt/btrfs
#btrfs subvolume create /mnt/btrfs/subvol
#mount -o subvol=subvol,context=system_u:object_r:nfs_t:s0 /dev/sda5
/mnt/test
kernel message:
SELinux: mount invalid. Same superblock, different security settings
for (dev sda5, type btrfs)
[REASON]
This happens because btrfs will call vfs_kern_mount() and then
mount_subtree() to handle subvolume name lookup.
First mount will cut off all the security lables and when it comes to
the second vfs_kern_mount(), it has no security label now.
[FIX]
This patch will makes btrfs behavior much more like nfs,
which has the type flag FS_BINARY_MOUNTDATA,
making btrfs handles the security label internally.
So security label will be set in the real mount time and won't lose
label when use with "subvol=" mount option.
