This one fixes a bug where once manage mode is set, the -a short option
is no longer parsed correctly (true of grow mode as well). This happens
because when you switch the short opts to the bitmap_auto version, it
specifies that the argument must follow a, yet the loop expects to get
an undecorated option and parse it as the disk dev instead of trying to
parse optarg. So, create a new short opt array that is used for manage
and grow that doesn't list a as having an argument.
udev likes to get information about a device as key=value pairs so it
can create disk/by-id links etc. So add --export flag which causes
the output of --detail to easily parsable.

This can be used to bootstrape homehost tagging.
If no arrays are found that are tagged, we look for any array
and tag it.

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.

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
support in monitor mode.
This patch adds exactly that.

Currently this includes
--write-behind to set level of write-behind supported
--write-mostly to flag devices as write-mostly.
