[PULL REQUEST] md - various fixed for 2.6.30

Hi Linus,
a few more md fixes turned up through on going testing.

A couple involve refining the user-space interface (sysfs) so that
some of the recent features can be used reliably.

The 'bitmap' fix isn't strictly a bug fix, but is reduces a fair
amount of CPU wastage.

The "don't use locked_ioctl" patch is again strictly not a bug fix,
but it is so trivial it didn't seem worth leaving it for .31.
It just tells the block layer that md doesn't need lock_kernel, even
for ioctls.

Thanks,
NeilBrown
