Hi Abu... > How the used pages reclaimed? Say if there is no swap space. Good question. I answer this because without looking at the codes: If we don't enable swap, I think this will happen: - If the page belongs to page cache, I think it will be discarded, but first the kernel will make sure the data is sync-ed to the backing file - If the page has backing file (in case on mmaped file), the page will be discarded after its data have been sync-ed - If it is an anymous page, it will be kept on RAM unless the user explicitly ask it to be freed.
