Subject: [PATCH 23/61] imsm: introduce get_disk_slot_in_dev()
|
|
Patch-mainline: mdadm-4.2+
|
|
References: jsc#PED-1009
|
|
|
|
The routine was added to remove unnecessary get_imsm_dev() and
|
|
get_imsm_map() calls, used only to determine disk slot.
|
|
|
|
Additionally, enum for IMSM return statues was added for further usage.
