PATCH 1/1 MD: prepare RAID10 for inclusion in dm-raid.c
Neil,
Here's a couple patches that are necessary for MD before I can add RAID10 to the list of supported personalities through dm-raid.c:
1) md-raid10-rename-mirror_info.patch
2) md-raid1-rename-mirror_info.patch
3) md-move-IO_BLOCKED-to-md_h.patch
4) md-export-md_raid10_congested.patch
I'll send the patch that enables raid10 as a separate patch that depends on this patch set and a couple of DM patches.

Can you explain a bit more detailed for me, what is this about? I.e. from
my point of view dm-raid and md-raid and fully separated but looks like I'm wrong and missing something.

drivers/md/dm-raid.c is a device-mapper target that provides access to the MD personalities. So far, MD's RAID 1/4/5/6 have been made available to the device-mapper interface through this module. We are laying the ground work here for RAID10 to be made available in the same way.
You may wish to have a look at linux/Documentation/device-mapper/dm-raid.txt for additional information. Also note that in "[PATCH 4 of 4] MD RAID10: Export md_raid10_congested", I referenced a couple of other times that these types of changes were necessary.
Thanks,
brassow
