- Make Cc be a client of Mm - Cc now creates a section object for each Shared cache map it creates - Some functions where introduced into Mm in order to let Cc make notice of dirtified pages, file flushes & purges, etc. - Make Mm the real master of how pages are kept in memory for mapped files (including cached files) - Keep track of dirty pages - Do not dismiss pages as soon as section object are closed - Fine tune the balancer to account for this changes (far from perfect yet) - Those changes are incompatbile with fastfat -> enable fastfat_new - Make Cc routines compatible with it, esp. regarding file locking, write-behind, etc.
