Please > check the details as below: Thanks for the testing. After looking at the test data below more carefully, I found that there is no perf hotspot of the shrink_slab(). That is, is the memory reclamation not triggered during the test? If this is the case, the only difference between 42c9db3970483 and f95bdb700bc6b is that there is one more call to synchronize_srcu(), and no one is in the critical section of shrinker_srcu at this time. It is strange that this can cause such a large performance regression, I will try to reproduce and continue to investigate the cause.
