Sorry, I got the before and after mixed up.
In addition, I also have some related questions to consult:
1. Will page fault exceptions be delayed during the writeback processing?
2. Since the loop device uses a work queue to handle requests, when
the system load is relatively high, will it have a relatively large
impact on the latency of page fault exceptions? Is there any way to solve
this problem?
