| Name | Describe | 
|---|---|
| try_to_free_mem_cgroup_pages | |
| balance_pgdat | For kswapd, balance_pgdat() will reclaim pages across a node from zones* that are eligible for use by the caller until at least one zone is* balanced.* Returns the order kswapd finished reclaiming at. | 
| __perform_reclaim | Perform direct synchronous page reclaim | 
| swap_readpage | |
| mem_cgroup_handle_over_high | Scheduled by try_charge() to be executed from the userland return path* and reclaims memory over the high limit. | 
| blkcg_maybe_throttle_blkg | This is called when we want to actually walk up the hierarchy and check to* see if we need to throttle, and then actually throttle if there is some* accumulated delay. This should only be called upon return to user space so |
