Subject: [RHEL7.5 PATCH 095/169] Detail: determine array state from sysfs
|
|
|
b7f731 |
|
|
|
b7f731 |
This is easily obtained from sysfs as part of the existing call to
|
|
|
b7f731 |
sysfs_read() and it simplifies the code a little too.
|
|
|
b7f731 |
|
|
|
b7f731 |
Another small step in the process of getting rid of the GET_ARRAY_STATE
|
|
|
b7f731 |
ioctl.
