Note that vm_swa_full is defined the following way #define vm_swap_full() (nr_swap_pages*2 < total_swap_pages) This means that vm_swap_full is true when more than 50% of swap are in use. The printed flag will therefore only be cleared if swap use falls to less than half. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
