Subject: [PATCH] report the correct size for partitions
|
|
|
e30bb2 |
|
|
|
e30bb2 |
If you use a partition instead of the whole device as the backstore device,
|
|
|
e30bb2 |
rtslib will always report its size as 0 bytes.
|
|
|
e30bb2 |
|
|
|
e30bb2 |
This happens because rtslib tries to read the "queue/logical_block_size"
|
|
|
e30bb2 |
attribute, which can only be found in the parent's node.
|
|
|
e30bb2 |
This patch fixes the bug by loading the parent node's attributes if
|
|
|
e30bb2 |
it detects that the device is a partition.
