With this patch, anon pages of inactive tasks can be reclaimed, depending on memory pressure. Memory pressure is detected using vmpressure events. 'N' best tasks in terms of anon size is selected and pages proportional to their tasksize is reclaimed. The total number of pages reclaimed at each run of the swap work, can be tuned from userspace, the default being SWAP_CLUSTER_MAX * 32. The patch also adds tracepoints to debug and tune the feature. echo 1 > /sys/module/process_reclaim/parameters/enable_process_reclaim to enable the feature. echo <pages> > /sys/module/process_reclaim/parameters/per_swap_size, to set the number of pages reclaimed in each scan. /sys/module/process_reclaim/parameters/reclaim_avg_efficiency, provides the average efficiency (scan to reclaim ratio) of the algorithm. /sys/module/process_reclaim/parameters/swap_eff_win, to set the window period (in unit of number of times reclaim is triggered) to detect low efficiency runs. /sys/module/process_reclaim/parameters/swap_opt_eff, to set the optimal efficiency threshold for low efficiency detection.
