They should show up in -next shortly. Probably the most interesting are the last few which provide support for converting a raid1 into a raid5, and a raid5 into a raid6. I plan to do some more work here so the code might change a bit before final submission, as I work out how best ot factor the code. mdadm doesn't current support these conversions, but you can simply echo raid5 > /sys/block/md0/md/level to change a 2-drive raid1 into a raid5. Similarly for 5->6 The raid6 array created will have a somewhat unusual layout in that all the Q blocks will be on the last drive. Later I'll create functionality to restripe the array so that the Q block is rotated around all the drives as you would expect. Comments and testing very welcome. Thanks, NeilBrown
