      [PATCH] md: fix a few problems with the interface (sysfs and ioctl) to md · 3f9d7b0d
      由 NeilBrown 提交于 
      While developing more functionality in mdadm I found some bugs in md...

- When we remove a device from an inactive array (write 'remove' to
  the 'state' sysfs file - see 'state_store') would should not
  update the superblock information - as we may not have
  read and processed it all properly yet.

- initialise all raid_disk entries to '-1' else the 'slot sysfs file
  will claim '0' for all devices in an array before the array is
  started.

- all '\n' not to be present at the end of words written to
  sysfs files

- when we use SET_ARRAY_INFO to set the md metadata version,
  set the flag to say that there is persistant metadata.

- allow GET_BITMAP_FILE to be called on an array that hasn't
  been started yet.

      [PATCH] md: avoid backward event updates in md superblock when degraded. · 84692195
      由 NeilBrown 提交于 
      If we
  - shut down a clean array,
  - restart with one (or more) drive(s) missing
  - make some changes
  - pause, so that they array gets marked 'clean',
the event count on the superblock of included drives
will be the same as that of the removed drives.
So adding the removed drive back in will cause it
to be included with no resync.

To avoid this, we only update the eventcount backwards when the array
is not degraded.  In this case there can (should) be no non-connected
drives that we can get confused with, and this is the particular case
where updating-backwards is valuable.

      [PATCH] lockdep: annotate blkdev nesting · 663d440e
      由 Ingo Molnar 提交于 
      Teach special (recursive) locking code to the lock validator.

Effects on non-lockdep kernels:

- the introduction of the following function variants:

  extern struct block_device *open_partition_by_devnum(dev_t, unsigned);

  extern int blkdev_put_partition(struct block_device *);

  static int
  blkdev_get_whole(struct block_device *bdev, mode_t mode, unsigned flags);

 which on non-lockdep are the same as open_by_devnum(), blkdev_put()
 and blkdev_get().

- a subclass parameter to do_open(). [unused on non-lockdep]

- a subclass parameter to __blkdev_put(), which is a new internal
  function for the main blkdev_put*() functions. [parameter unused
  on non-lockdep kernels, except for two sanity check WARN_ON()s]

these functions carry no semantical difference - they only express
object dependencies towards the lockdep subsystem.
