Hi, zsmalloc has only two fullness group to choose pages from during zs_malloc() and zs_compact(): - ALMOST_EMPTY for pages with usage ratio equal or less to 3/4 of total page capacity - ALMOST_FULL for pages with usage raio greater than 3/4 of total page capacity This leads to suboptimal page selection for both zs_malloc() and zs_compact(). This patchset reworks zsmalloc fullness grouping/classification.
