A new read policy 'device' is introduced with this patch, which when set
can pick the read_preferred device for reading. This tunable is for
advance users who knows what they are doing so that they have the
flexibility of making sure that reads are read from the device they
prefer.

For example:

$ cat /sys/fs/btrfs/UUID/read_policy
[pid] device

$echo 1 > /sys/fs/btrfs/UUID/devinfo/1/read_preferred

$echo device > /sys/fs/btrfs/UUID/read_policy

$cat /sys/fs/btrfs/UUID/read_policy
pid [device]

Preparatory patch to add new read_policy type 'device'.
Provides a sysfs interface to set the device state as read_preferred.

Signed-off-by: Anand Jain <anand.jain@oracle.com>

Add

 /sys/fs/btrfs/UUID/read_policy

attribute so that the read policy for the raid1 and raid10 chunks can be
tuned.

When this attribute is read, it shall show all available policies, with
active policy being with in [ ]. The read_policy attribute can be written
using one of the items listed in there.

For example:
  $cat /sys/fs/btrfs/UUID/read_policy
  [pid]
  $echo pid > /sys/fs/btrfs/UUID/read_policy

As of now we use %pid method to read stripped mirrored data, which means
process id determines the stripe id to be read. This type of routing
typically helps in a system with many small independent processes tying
to read random data. On the other hand the %pid based read IO policy is
inefficient because if there is a single process trying to read large
data the overall disk bandwidth remains under-utilized.

So this patch introduces read policy framework so that we could add more
read policies, such as IO routing based on device's wait-queue or manual
when we have a read-preferred device or a policy based on the target
storage caching.

The current codebase makes use of the zero-length array language

introduced in C99:

struct foo {
        int stuff;

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which

inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by

may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

Pull sound fixes from Takashi Iwai:
 "The only common change is the regression fix of the previous PCM fix
  patch for managed buffers while the rest are usual suspects, USB-audio

  The change for UAC2 clock validation workaround became a bit big, but
  the changes are fairly straightforward"
