Subject: [PATCH 57/66] imsm: define RAID_10 attribute
|
|
|
|
Add MPB_ATTRIB_RAID10_EXT attribute to support RAID 10
|
|
with more than 4 drives.
|
|
|
|
Allow more than 4 drives in imsm_orom_support_raid_disks_raid10().
|
|
|
|
This is one of last patches for introducing R10D4+ to imsm.
|
|
Only small adjustments in reshape behaviours are needed.
