Thanks for your thorough work on tmpfs "noswap": seems well-received by quite a few others, that's good. I've just a few comments on later patches (I don't understand why you went into those little rearrangements at the start of shmem_writepage(), but they seem harmless so I don't object), but wanted to ask here: You say "a common complaint about tmpfs is the inability to work without the page cache". Ehh? I don't understand that at all, and have never heard such a complaint. It doesn't affect the series itself (oh, Andrew has copied that text into the first patch), but please illuminate! Thanks, Hugh
