write_pieced_value: Include transfer size in byte-wise check
|
||
|
|
|
||
|
|
In write_pieced_value, when checking whether the data can be transferred
|
||
|
|
byte-wise, the current logic verifies the source- and destination offsets
|
||
|
|
to be byte-aligned, but not the transfer size. This is fixed.

||
|
|
