From: liujinbao1 <liujinb...@xiaomi.com>
By default, the gc_thread_func function fluctuates within
the range of min_sleep_time to max_sleep_time, and only
when gc_mode is GC_URGENT_HIGH, wait_ms can be specified
as urgent_sleep_time.For other algorithms, we may also want
to execute it periodically. After introducing this patch,
we can control the gc_thread_func function to run periodically
by setting the values of min_sleep_time and max_sleep_time to
be the same.
