Hi,
The WRITE_ODIRECT flag is only used in one place, and that code path
happens to also call blk_run_address_space. The introduction of this
flag, then, could result in the device being unplugged twice for every
I/O.
Further, with the batching changes in the next patch, we don't want an
O_DIRECT write to imply a queue unplug.

We currently use a 16 bit field (vlan_tci) to store VLAN ID/PRIO on a skb.
Null value is used as a special value, meaning vlan tagging not enabled.
This forbids use of null vlan ID.
As pointed by David, some drivers use the 3 high order bits (PRIO)
As VLAN ID is 12 bits, we can use the remaining bit (CFI) as a flag, and
allow null VLAN ID.
In case future code really wants to use VLAN_CFI_MASK, we'll have to use
a bit outside of vlan_tci.
#define VLAN_PRIO_MASK 0xe000 /* Priority Code Point */
#define VLAN_PRIO_SHIFT 13
#define VLAN_CFI_MASK 0x1000 /* Canonical Format Indicator */
#define VLAN_TAG_PRESENT VLAN_CFI_MASK

This patch is a version of RCU designed for !SMP provided for a
small-footprint RCU implementation. In particular, the
implementation of synchronize_rcu() is extremely lightweight and
high performance. It passes rcutorture testing in each of the
four relevant configurations (combinations of NO_HZ and PREEMPT)
on x86. This saves about 1K bytes compared to old Classic RCU
(which is no longer in mainline), and more than three kilobytes
compared to Hierarchical RCU (updated to 2.6.30):
CONFIG_TREE_RCU:
text data bss dec filename
183 4 0 187 kernel/rcupdate.o
2783 520 36 3339 kernel/rcutree.o
3526 Total (vs 4565 for v7)
CONFIG_TREE_PREEMPT_RCU:
text data bss dec filename
263 4 0 267 kernel/rcupdate.o
4594 776 52 5422 kernel/rcutree.o
5689 Total (6155 for v7)
CONFIG_TINY_RCU:
text data bss dec filename
96 4 0 100 kernel/rcupdate.o
734 24 0 758 kernel/rcutiny.o
858 Total (vs 848 for v7)
The above is for x86. Your mileage may vary on other platforms.
Further compression is possible, but is being procrastinated.
Changes from v7 (http://lkml.org/lkml/2009/10/9/388)
o Apply Lai Jiangshan's review comments (aside from
might_sleep() in synchronize_sched(), which is covered by SMP builds).
o Fix up expedited primitives.
Changes from v6 (http://lkml.org/lkml/2009/9/23/293).
o Forward ported to put it into the 2.6.33 stream.
o Added lockdep support.
o Make lightweight rcu_barrier.
Changes from v5 (http://lkml.org/lkml/2009/6/23/12).
o Ported to latest pre-2.6.32 merge window kernel.
- Renamed rcu_qsctr_inc() to rcu_sched_qs().
- Renamed rcu_bh_qsctr_inc() to rcu_bh_qs().
- Provided trivial rcu_cpu_notify().
- Provided trivial exit_rcu().
- Provided trivial rcu_needs_cpu().
- Fixed up the rcu_*_enter/exit() functions in linux/hardirq.h.
o Removed the dependence on EMBEDDED, with a view to making
TINY_RCU default for !SMP at some time in the future.
o Added (trivial) support for expedited grace periods.
Changes from v4 (http://lkml.org/lkml/2009/5/2/91) include:
o Squeeze the size down a bit further by removing the
->completed field from struct rcu_ctrlblk.
o This permits synchronize_rcu() to become the empty function.
Previous concerns about rcutorture were unfounded, as
rcutorture correctly handles a constant value from
rcu_batches_completed() and rcu_batches_completed_bh().
Changes from v3 (http://lkml.org/lkml/2009/3/29/221) include:
o Changed rcu_batches_completed(), rcu_batches_completed_bh()
rcu_enter_nohz(), rcu_exit_nohz(), rcu_nmi_enter(), and
rcu_nmi_exit(), to be static inlines, as suggested by David
Howells. Doing this saves about 100 bytes from rcutiny.o.
(The numbers between v3 and this v4 of the patch are not directly
comparable, since they are against different versions of Linux.)
Changes from v2 (http://lkml.org/lkml/2009/2/3/333) include:
o Fix whitespace issues.
o Change short-circuit "||" operator to instead be "+" in order
to fix performance bug noted by "kraai" on LWN.
(http://lwn.net/Articles/324348/)
Changes from v1 (http://lkml.org/lkml/2009/1/13/440) include:
o This version depends on EMBEDDED as well as !SMP, as suggested
by Ingo.
o Updated rcu_needs_cpu() to unconditionally return zero,
permitting the CPU to enter dynticks-idle mode at any time.
This works because callbacks can be invoked upon entry to
dynticks-idle mode.
o Paul is now OK with this being included, based on a poll at
the Kernel Miniconf at linux.conf.au, where about ten people said
that they cared about saving 900 bytes on single-CPU systems.
o Applies to both mainline and tip/core/rcu.

Make the hrtimer based events work for sysprof.
Whenever a swevent is scheduled out, the hrtimer is canceled.
When it is scheduled back in, the timer is restarted. This
happens every scheduler tick, which means the timer never
expired because it was getting repeatedly restarted over and
over with the same period.
To fix that, save the remaining time when disabling; when
reenabling, use that saved time as the period instead of the

virtio: add virtio IDs file
moved all device IDs into a single file. While the change itself is
a very good one, it can break userspace applications. For example
if a userspace tool wanted to get the ID of virtio_net it used to

does not include virtio_ids.h.
This patch moves all "#include <linux/virtio_ids.h>" from the C

The i2400m driver uses two different bits to distinguish how much the
driver is up. i2400m->ready is used to denote that the infrastructure
to communicate with the device is up and running. i2400m->updown is
used to indicate if 'ready' and the device is up and running, ready to
take control and data traffic.
However, all this was pretty dirty and not clear, with many open spots
where race conditions were present.
This commit cleans up the situation by:
- documenting the usage of both bits
- setting them only in specific, well controlled places
(i2400m_dev_start, i2400m_dev_stop)
- ensuring the i2400m workqueue can't get in the middle of the
setting by flushing it when i2400m->ready is set to zero. This
allows the report hook not having to check again for the bit to be
set [rx.c:i2400m_report_hook_work()].
- using i2400m->updown to determine if the device is up and running
instead of the wimax state in i2400m_dev_reset_handle().
- not loosing missed messages sent by the hardware before
i2400m->ready is set. In rx.c, whatever the device sends can be
sent to user space over the message pipes as soon as the wimax
device is registered, so don't wait for i2400m->ready to be set.

The i2400m based devices can get in a sort of a deadlock some times;
when they boot, they send a reboot "barker" (a magic number) and then
the driver has to echo that same barker to ack reception
(echo/ack). Then the device does a final ack by sending an ACK barker.
The first time this happens, we don't know ahead of time with barker
the device is going to send, as different device models and SKUs will
send different barker depending on the EEPROM programming.
If the device has sent the barker before the driver has been able to
read it, the driver looses, as it doesn't know which barker it has to
echo/ack back. With older devices, we tried a couple of combinations
and that always worked; but now, with adding support for more, in
which we have an unlimited number of new barkers, that is not an
option.
So we rework said case so that when the device gets stuck, we just
cycle through all the known types until one forces the device to send
an ack. Otherwise, the driver gives up and aborts.

The i2400m based devices can boot two main types of firmware images:
signed and non-signed. Signed images have signature data included that
must match that of a certificate stored in the device.
Currently the code is making the decission on what type of firmware
load (signed vs non-signed) is going to be loaded based on a hardcoded
decission in __i2400m_ack_verify(), based on the barker the device
sent upon boot.
This is not flexible enough as future hardware will emit more barkers;
thus the bit has to be set in a place where there is better knowledge
of what is going on. This will be done in follow-up commits -- however
this patch paves the way for it.
So the querying of the mode is packed into i2400m_boot_is_signed();
the main changes are just using i2400m_boot_is_signed() to determine
the method to follow and setting i2400m->sboot in
i2400m_is_boot_barker(). The modifications in i2400m_dnload_init() and
i2400m_dnload_finalize() are just reorganizing the order of the if
blocks and thus look larger than they really are.

To support for ahash algorithms, we add a pointer to a
crypto_ahash to ah_data.

Remove unused digest_alg and hash_alg structs from crypto_alg union and
kill their definitions. This also ensures that old-style digest/hash
algorithms maintained out of tree will break at build time rather than
oopsing at runtime.

6941c3a0 disabled compilation of the legacy digest code but didn't
actually remove it. Rectify this. Also, remove the crypto_hash_type
extern declaration from algapi.h now that the struct is gone.
