Subject: [PATCH] Create: Block rounding size to max
|
|
Git-commit: 22dc741f63e6403d59c2c14f56fd4791265f9bbb
|
|
Patch-mainline: mdadm-4.1+
|
|
References: jsc#SLE-10078, jsc#SLE-9348
|
|
|
|
When passed size is smaller than chunk, mdadm rounds it to 0 but 0 there
|
|
means max available space.
|
|
Block it for every metadata. Remove the same check from imsm routine.
