RH-Commit: [27/41] eaa05c39109b57a119752ad3df66f4c2ace2cbe4
|
||
|
|
|
||
|
|
dump_calculate_size() sums up all the sizes of the guest memory
|
||
|
|
blocks. Since we already have a function that calculates the size of a
|
||
|
|
single memory block (dump_get_memblock_size()) we can simply iterate
|
||
|
|
over the blocks and use the function instead of calculating the size
|
||
|
|
ourselves.
