Jörn Engel announced LogFS, "a scalable flash filesystem." The project's home page notes that LogFS aims to be the successor of JFFS2, "the two main problems of JFFS2 are memory consumption and mount time. Unlike most filesystems, there is no tree structure of any sorts on the medium, so the complete medium needs to be scanned at mount time and a tree structure kept in-memory while the filesystem is mounted. With bigger devices, both mount time and memory consumption increase linearly. JFFS2 has recently gained summary support, which helps reduce mount time by a constant factor. Linear scalability remains. YAFFS also appears to be better by a constant factor, yet still scales linearly."
