(which is not what I want). It'll reclaim unused pagecache pages. What effect that has on idioticfs^Wtmpfs pages depends on the state of the pages. If they're attached to tmpfs inodes then they won't be reclaimed because they have no backing store. If they're attached to swapcache then they won't be reclaimed because they have no superblock. So I guess you got lucky. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
