Change io_locking to allow processing flush in separate thread.

Because we have DMF_BLOCK_IO already set, any possible
new ios are queued in dm_requests now.

In the case of interrupting previous wait there can be more
ios queued (we unlocked io_lock for a while) but this is safe.

Make sure we have enough room for all the GR registers or we'll end up

It's possible that the caller of sysfs_remove_group messed up and passed in an attribute group that was not really registered to this kobject.  But don't panic for such a foolish error, spit out a warning about what happened, and continue on our way safely.

The original patch breaks BIOS updates on all Dell machines. The path to
the firmware file for the dell_rbu driver changes, which breaks all of
the userspace tools which rely on it.

Note that this patch re-introduces a problem with i2c name collision
that was previously fixed by this patch.

The "whole_disk" attribute was not properly converted in the block
device conversion earlier, and if the file is read, bad things can
happen.  This patch fixes this, making the attribute an empty one,
preserving the original functionality.

Many thanks to David Miller for finding this, and pointing me in the
proper place within the block code to look.
