md: don't allow bitmap file to be added to raid0/linear. (2014-08-08 15:43:20 +1000)

md updates for 3.17

Most interesting is that md devices (major == 9) with
minor numbers of 512 or more will no longer be created
simply by opening a block device file. They can only
be created by writing to
The 'auto-create-on-open' semantic is cumbersome and we
need to start moving away from it.

NeilBrown (4):
md/raid1,raid10: always abort recover on write error.
md: disable probing for md devices 512 and over.
md/raid0: check for bitmap compatability when changing raid levels.
md: don't allow bitmap file to be added to raid0/linear.

Xiao Ni (1):
md: Recovery speed is wrong
