Neil Brown 05697ec1e2 Make homehost information appear in superblock. 
When an array is created, if the homehost is know,
the superblock gets it, either in the uuid, (via sha1)
or in the name field.

Neil Brown f1ae21c411 Arrange the 'auto' setting in mdadm.conf can choose default type. 
So when you say auto=md or auto=part in mdadm.conf, it give a preference
for type of array, but standard name will override.

But --auto=md is more insistant.

FIXME  I'm not at all happy about handling of names that already exist.
  I don't think that should be removed if the device is active.

Neil Brown 4ccdb95600 Use O_DIRECT to read bitmap files. 
A pending patch to the kernel causes bitmap file updates
to not go through the page cache, so O_DIRECT is needed to
ensure that we read current data.

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.

From: ross@jose.lug.udel.edu (Ross Vandegrift)

Hi Neil,

While adding the text message mode, I saw a FIXME asking for syslog
support in monitor mode.

This patch adds exactly that.
