Neil Brown b8a8ccf945 New flag --no-degraded 
Use to avoid starting arrays if there are
fewer devices available than last time the array was started.
This is only needed with --scan, as with --scan, that behaviour
is the default.

Neil Brown 1bfdbe01ff Limit size of bitmap to 2million chunks. 
When creating a file bitmap, choose a default size that
results in fewer than 2^21 chunks.  Without this kmalloc
failure in the kernel becomes likely.

Neil Brown 06b0d78675 Allow resize to backup to a file. 
To support resizing an array without a spare, mdadm now understands
  --backup-file=
which should point to a file for storing a backup of critical data.
This can be given to --grow which will create the file, or
--assemble which will restore from the file if needed.

Hi Neil,

While adding the text message mode, I saw a FIXME asking for syslog
