      Anatol Pomozov authored
      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.

      First round of IIO fixes for 3.12
      
      A series of wrong 'struct dev' assumptions in suspend/resume callbacks
      following on from this issue being identified in a new driver review.
      One to watch out for in future.
      
      A number of driver specific fixes
      1) at91 - fix a overflow in clock rate computation
      2) dummy - Kconfig dependency issue
      3) isl29018 - uninitialized value
      4) hmc5843 - measurement conversion bug introduced by recent cleanup.
      5) ade7854-spi - wrong return value.
      
      Some IIO core fixes
      1) Wrong value picked up for event code creation for a modified channel
      2) A null dereference on failure to initialize a buffer after no buffer has
         been in use, when using the available_scan_masks approach.
      3) Sampling not stopped when a device is removed. Effects forced removal
         such as hot unplugging.
      4) Prevent device going away if a chrdev is still open in userspace.
      5) Prevent race on chardev opening and device being freed.
      6) Add a missing iio_buffer_init in the call back buffer.
      
      These last few are the first part of a set from Lars-Peter Clausen who
      has been taking a closer look at our removal paths and buffer handling
      than anyone has for quite some time.

      block: Add nr_bios to block_rq_remap tracepoint · 75afb352
      Jun'ichi Nomura authored
      Adding the number of bios in a remapped request to 'block_rq_remap'
      tracepoint.
      
      Request remapper clones bios in a request to track the completion
      status of each bio. So the number of bios can be useful information
      for investigation.

      Btrfs: create the uuid tree on remount rw · 94aebfb2
      Josef Bacik authored
      Users have been complaining of the uuid tree stuff warning that there is no uuid
      root when trying to do snapshot operations.  This is because if you mount -o ro
      we will not create the uuid tree.  But then if you mount -o rw,remount we will
      still not create it and then any subsequent snapshot/subvol operations you try
      to do will fail gloriously.  Fix this by creating the uuid_root on remount rw if
      it was not already there.  Thanks,

      btrfs: change extent-same to copy entire argument struct · cbf8b8ca
      Mark Fasheh authored
      btrfs_ioctl_file_extent_same() uses __put_user_unaligned() to copy some data
      back to it's argument struct. Unfortunately, not all architectures provide
      __put_user_unaligned(), so compiles break on them if btrfs is selected.
      
      Instead, just copy the whole struct in / out at the start and end of
      operations, respectively.

      Btrfs: dir_inode_operations should use btrfs_update_time also · 93fd63c2
      Guangyu Sun authored
      Commit 2bc55652 (Btrfs: don't update atime on
      RO subvolumes) ensures that the access time of an inode is not updated when
      the inode lives in a read-only subvolume.
      However, if a directory on a read-only subvolume is accessed, the atime is
      updated. This results in a write operation to a read-only subvolume. I
      believe that access times should never be updated on read-only subvolumes.
      
      To reproduce:
      
       # mkfs.btrfs -f /dev/dm-3
       (...)
       # mount /dev/dm-3 /mnt
       # btrfs subvol create /mnt/sub
       	Create subvolume '/mnt/sub'
       # mkdir /mnt/sub/dir
       # echo "abc" > /mnt/sub/dir/file
       # btrfs subvol snapshot -r /mnt/sub /mnt/rosnap
       	Create a readonly snapshot of '/mnt/sub' in '/mnt/rosnap'
