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


I've nearly isolated another bug - raid6 can sometime get corrupt during
recovery.  Once that is properly understood and tested I'll send it separately.

Thanks,
NeilBrown

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
   /sys/module/md_mod/parameters/new_array
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
