Currently, during CPU hotplug, the cpuset callbacks modify the cpusets
to reflect the state of the system, and this handling is asymmetric.
That is, upon CPU offline, that CPU is removed from all cpusets. However
when it comes back online, it is put back only to the root cpuset.
This gives rise to a significant problem during suspend/resume. During
suspend, we offline all non-boot cpus and during resume we online them back.
Which means, after a resume, all cpusets (except the root cpuset) will be
restricted to just one single CPU (the boot cpu). But the whole point of
suspend/resume is to restore the system to a state which is as close as
possible to how it was before suspend.
So to fix this, don't touch cpusets during suspend/resume. That is, modify
the cpuset-related CPU hotplug callback to just ignore CPU hotplug when it
is initiated as part of the suspend/resume sequence.

The cifs code will attempt to open files on lookup under certain
circumstances. What happens though if we find that the file we opened
was actually a FIFO or other special file?
Currently, the open filehandle just ends up being leaked leading to
a dentry refcount mismatch and oops on umount. Fix this by having the
code close the filehandle on the server if it turns out not to be a
regular file. While we're at it, change this spaghetti if statement
into a switch too.

Two fixes to fix a memory corruption bug when WC pages never get
converted back to WB but end up being recycled in the general memory
pool as WC.
There is a better way of fixing this, but there is not enough time to do
the full benchmarking to pick one of the right options - so picking the
one that favors stability for right now.

Currently we do inc/drop_nlink for a parent directory for every
mkdir/rmdir calls. That's wrong when Unix extensions are disabled
because in this case a server doesn't follow the same semantic and
returns the old value on the next QueryInfo request. As the result,
we update our value with the server one and then decrement it on
every rmdir call - go to negative nlink values.
Fix this by removing inc/drop_nlink for the parent directory from
mkdir/rmdir, setting it for a revalidation and ignoring NumberOfLinks
for directories when Unix extensions are disabled.

25) When we added VF (virtual function) attributes for network device
dumps, this potentially bloats up the size of the dump of one
network device such that the dump size is too large for the buffer
allocated by properly written netlink applications.
In particular, if you add 255 VFs to a network device, parts of
GLIBC stop working.
To fix this, we add an attribute that is used to turn on these
extended portions of the network device dump. Sophisticaed
applications like 'ip' that want to see this stuff will be changed
to set the attribute, whereas things like GLIBC that don't care
about VFs simply will not, and therefore won't be busted by the
mere presence of VFs on a network device.
Thanks to the tireless work of Greg Rose on this fix.

A driver xmit function is not allowed to change skb without special
care.
mlx4_en_xmit() should not call skb_reset_mac_header() and instead should
use skb->data to access ethernet header.
This removes a dumb test : if (ethh && ethh->h_dest)
Also remove this slow mlx4_en_mac_to_u64() call, we can use
get_unaligned() to get faster code.

you to selectively send conntrack entries to user-space by

This patch allows you to pass a data pointer that can be
accessed from the dump callback.
Netfilter is going to use this patch to provide filtered dumps
to user-space. This is specifically interesting in ctnetlink that
may handle lots of conntrack entries. We can save precious
cycles by skipping the conversion to TLV format of conntrack
entries that are not interesting for user-space.
More specifically, ctnetlink will include one operation to allow
to filter the dumping of conntrack entries by ctmark values.

The autofs compat handling fix caused a compile failure when
CONFIG_COMPAT isn't defined.
Instead of adding random #ifdef'fery in autofs, let's just make the
compat helpers earlier to use: without CONFIG_COMPAT, is_compat_task()
just hardcodes to zero.
We could probably do something similar for a number of other cases where
we have #ifdef's in code, but this is the low-hanging fruit.

When the autofs protocol version 5 packet type was added in commit
5c0a32fc2cd0 ("autofs4: add new packet type for v5 communications"), it
obvously tried quite hard to be word-size agnostic, and uses explicitly
sized fields that are all correctly aligned.
However, with the final "char name[NAME_MAX+1]" array at the end, the
actual size of the structure ends up being not very well defined:
because the struct isn't marked 'packed', doing a "sizeof()" on it will
align the size of the struct up to the biggest alignment of the members
it has.
And despite all the members being the same, the alignment of them is
different: a "__u64" has 4-byte alignment on x86-32, but native 8-byte
alignment on x86-64. And while 'NAME_MAX+1' ends up being a nice round
number (256), the name[] array starts out a 4-byte aligned.
End result: the "packed" size of the structure is 300 bytes: 4-byte, but
not 8-byte aligned.
As a result, despite all the fields being in the same place on all
architectures, sizeof() will round up that size to 304 bytes on
architectures that have 8-byte alignment for u64.
Note that this is *not* a problem for 32-bit compat mode on POWER, since
there __u64 is 8-byte aligned even in 32-bit mode. But on x86, 32-bit
and 64-bit alignment is different for 64-bit entities, and as a result
the structure that has exactly the same layout has different sizes.
So on x86-64, but no other architecture, we will just subtract 4 from
the size of the structure when running in a compat task. That way we
will write the properly sized packet that user mode expects.
Not pretty. Sadly, this very subtle, and unnecessary, size difference
has been encoded in user space that wants to read packets of *exactly*
the right size, and will refuse to touch anything else.

It used to be that minors where 8 bit. But now they
are actually 20 bit. So the fix is simplicity itself.
I've tested with 300 devices and all user-mode utils
work just fine. I have also mechanically added 10,000
to the ida (so devices are /dev/osd10000, /dev/osd10001 ...)
and was able to mkfs an exofs filesystem and access osds
from user-mode.
All the open-osd user-mode code uses the same library
to access devices through their symbolic names in
/dev/osdX so I'd say it's pretty safe. (Well tested)
This patch is very important because some of the systems
that will be deploying the 3.2 pnfs-objects code are larger
than 64 OSDs and will stop to work properly when reaching
that number.

When pre-allocating skbs for received packets, we set ip_summed =
CHECKSUM_UNNCESSARY. We used to change it back to CHECKSUM_NONE when
the received packet had an incorrect checksum or unhandled protocol.
Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid
some skb->ip_summed initializations') mistakenly replaced the latter
assignment with a DEBUG-only assertion that ip_summed ==
CHECKSUM_NONE. This assertion is always false, but it seems no-one
has exercised this code path in a DEBUG build.
Fix this by moving our assignment of CHECKSUM_UNNECESSARY into
efx_rx_packet_gro().

This patch fixes a (mostly cosmetic) bug introduced by the patch
'ppp: Use SKB queue abstraction interfaces in fragment processing'
found here: http://www.spinics.net/lists/netdev/msg153312.html
The above patch rewrote and moved the code responsible for cleaning
up discarded fragments but the new code does not catch every case
where this is necessary. This results in some discarded fragments
remaining in the queue, and triggering a 'bad seq' error on the
subsequent call to ppp_mp_reconstruct. Fragments are discarded
whenever other fragments of the same frame have been lost.
This can generate a lot of unwanted and misleading log messages.
This patch also adds additional detail to the debug logging to
make it clearer which fragments were lost and which other fragments
were discarded as a result of losses. (Run pppd with 'kdebug 1'
option to enable debug logging.)

The original spelling and bad word choice makes these comments hard to read.

Removes all references to the global variable that records whether
TIPC is running in "single node" mode or "network" mode, since this
information can be easily deduced from the global variable that
records TIPC's network address. (i.e. a non-zero network address
means that TIPC is running in network mode.)
The changes made update most existing mode-based checks to use the
network address global variable. A few checks that are no longer
needed are removed entirely, along with any associated code lying on
non-executable control paths.

Removes all references to TIPC's "not running" mode, since the
removal of support for the native API means that there is no longer
any way to interact with TIPC if it has not been initialized.
The changes made consist of removing mode-based checks that are no
longer needed, along with any associated code lying on non-executable
control paths.
