There is no need to clear all mem in add_domains, beacause memcpy will write the front section. We only need to clear the mem in the end, which will improve the performance. Signed-off-by: nocjj <1250062498@qq.com>

Subject: [PATCH] performance: change memset location
|
|
|
|
There is no need to clear all mem in add_domains, beacause memcpy will
|
|
write the front section. We only need to clear the mem in the end, which
|
|
will improve the performance.
