ION system heap keeps pages in its pool for better performance. When the system is under memory pressure, slab shrinker calls the callback registered and then the pages pooled get freed. When the shrinker is called, it checks gfp_mask and determines whether the pages from highmem need to be freed or the pages from lowmem. Usually, slab shrinker is invoked on kswapd context which gfp_mask is always GFP_KERNEL, so only lowmem pages are released on kswapd context. This means that highmem pages in the pool are never reclaimed until direct reclaim occurs. This can be problematic when the page pool holds excessive amounts of highmem. For now, the shrinker callback cannot know exactly which zone should be targeted for reclamation, as enough information are not passed to. Thus, it makes sense to shrink both lowmem and highmem zone on kswapd context. Reported-by:

The page pool uses an internal data structure, ion_page_pool_item, for wrapping pooled pages and constructing a list. As the struct page already provides ways for doing exactly the same thing, we do not need to reinvent the wheel. This commit removes the data structure and slab allocations for it. Signed-off-by:

ion_page_pool_total() returns the total number of pages in the pool. Depending on the argument passed, it counts highmem pages in or not. This commit simplifies the code lines for better readability. Signed-off-by:

There are references to four undefined Kconfig macros in the code. Commit 8542373d ("Staging: rtl8812ae: remove undefined Kconfig macros") removed identical references from another staging driver, but they resurfaced in rtl8192ee. Remove these again as the checks for them still will always evaluate to false. Signed-off-by:
