Simplistig locking for --incremental.
...
From: Bill Nottingham <notting@redhat.com>
mdadm --incremental doesn't really do any locking. If you get multiple
events in parallel for the same device (that has not yet started), they
will all go down the path to create the array. One will succeed, the
rest will have SET_ARRAY_INFO die with -EBUSY (md: array mdX already has disks!)
and will exit without adding the disk.
Original bug report is: https://bugzilla.redhat.com/show_bug.cgi?id=433932
This is solved by adding very very rudimentary locking. Incremental() now
opens the device with O_EXCL to ensure only one invocation is frobbing the
array at once. A simple loop just tries to open 5 times a second for 5
seconds. If the array stays locked that long, you probably have bigger
issues.

This would only create partitioned devices if the device name was a
'standard' name. This this patch, any name will work.

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.
