54ac005adc V4L/DVB (6185): cx88-alsa: Add mute controls, change control names
Add two mute controls.  One mutes everything, the other just mutes the analog
pass-through output.

Rename the existing volume control.  The controls are now:
Playback Volume
Playback Switch
Capture Switch

These names might seem odd, but I believe they are more correct.  The previous
"Capture Volume" control didn't actually effect the volume of the captured
audio.  Instead it controls the volume of the analog pass-thought output.  It
appears that pass-through controls like this are usually considered to be in
the playback direction, not capture.  For example, "CAPTURE feedback Playback
Volume" is the name used for a control that appears to have the same effect in
the ca0106 driver.  We only have one volume control, so we can omit the
"CAPTURE feedback" part.

If someone where to add PCM playback support to the driver, then this would be
the volume control.

fe97e2aa05 dm mpath: hp retry if not ready
This patch adds retries to the hp hardware handler, and utilizes the
MP_RETRY flag of dm-multipath.  For now in the hp handler, if we get a
pg_init completed with a check condition we just assume we can retry the
pg_init command.  We make this assumption because of incomplete data on
specific check condition code of the HP hardware, and because testing
has shown the HP path initialization command to be idempotent.
The number of times we retry is settable via the "pg_init_retries"
multipath map feature.

c9e45581ad dm mpath: add retry pg init
This patch allows a failed path group initialisation command to be retried.

It adds a generic MP_RETRY flag and a "pg_init_retries" feature to
device-mapper multipath which limits the number of retries.

1. A hw handler sends a path initialization command to the storage and
the command completes with an error code indicating the command
should be retried.

2. The hardware handler calls dm_pg_init_complete() with MP_RETRY
set in err_flags to ask the dm multipath core to retry.

3. If the retry limit has not been exceeded, pg_init() is retried.
Otherwise fail_path() is called.

If you are using the userspace multipath-tools or device-mapper-multipath
package, you can set pg_init_retries in the 'device' section of your
/etc/multipath.conf file. For example:

features                "2 pg_init_retries 7"

The number of PG retries attempted is reported in the 'dmsetup status' output.

ae9da83f6d dm: fix thaw_bdev
This patch fixes a bd_mount_sem counter corruption bug in device-mapper.

thaw_bdev() should be called only when freeze_bdev() was called for the
device.
Otherwise, thaw_bdev() will up bd_mount_sem and corrupt the semaphore counter.
struct block_device with the corrupted semaphore may remain in slab cache
and be reused later.

Attached patch will fix it by calling unlock_fs() instead.
unlock_fs() will determine whether it should call thaw_bdev()
by checking the device is frozen or not.

Easy reproducer is:
  #!/bin/sh
  while [ 1 ]; do
     dmsetup --notable create a
     dmsetup --nolockfs suspend a
     dmsetup remove a
  done

It's not easy to see the effect of corrupted semaphore.
So I have tested with putting printk below in bdev_alloc_inode():
        if (atomic_read(&ei->bdev.bd_mount_sem.count) != 1)
                printk(KERN_DEBUG "Incorrect semaphore count = %d (%p)\n",
                        atomic_read(&ei->bdev.bd_mount_sem.count),
                        &ei->bdev);

Without the patch, I saw something like:
 Incorrect semaphore count = 17 (f2ab91c0)

With the patch, the message didn't appear.

The bug was introduced in 2.6.16 with this bug fix:

commit d9dde59ba0
Date:   Fri Feb 24 13:04:24 2006 -0800

    [PATCH] dm: missing bdput/thaw_bdev at removal

    Need to unfreeze and release bdev otherwise the bdev inode with
    inconsistent state is reused later and cause problem.

and backported to 2.6.15.5.

It occurs only in free_dev(), which is called only when the dm device is
removed.  The buggy code is executed only if md->suspended_bdev is
non-NULL and that can happen only when the device was suspended without
noflush.
