Normal filesystems have a backing stor= e plus a page cache. Tmpfs removes the backing store and keeps everythin= g in the page cache. XIP removes the page cache and leaves everything in the backing store - which is memory. Would tmpfs plus XIP remove both the page cache and the backing store? J=C3=B6rn --=20 Data dominates. If you've chosen the right data structures and organize= d things well, the algorithms will almost always be self-evident.
