Subject: [PATCH 40/41] mdadm: fix grow segfault for IMSM
|
|
|
|
If sc is not initialized, there is possibility that sc.pols is not zeroed
|
|
and it causes segfault.
|
|
|
|
Add missing initialization.
|
|
Add missing dev_policy_free() in two places.
|
|
|
|
Fixes: f656201188d7 ("mdadm: drop get_required_spare_criteria()")
