Subject: [RHEL7.5 PATCH 114/169] container_members_max_degradation: Switch
|
|
|
b7f731 |
to using syfs for disk info
|
|
|
b7f731 |
|
|
|
b7f731 |
With sysfs now providing the necessary active_disks info, switch to
|
|
|
b7f731 |
sysfs and eliminate one more use of md_get_array_info(). We can do
|
|
|
b7f731 |
this unconditionally since we wouldn't get here witout sysfs being
|
|
|
b7f731 |
available.
