- Added cleaner allocation of shm addresses by moving the allocation to do_mmap(). - Added deletion routine for all objects: shadow, vm_file of type vfs_file, shm_file, etc. - Need to make sure objects get deleted properly after exit(). - Currently we allow a single, unique virtual address for each shm segment.
