-/*
- * tiny-shmem.c: simple shmemfs and tmpfs using ramfs code
- *
- * Matt Mackall <mpm@selenic.com> January, 2004
- * derived from mm/shmem.c and fs/ramfs/inode.c
- *
- * This is intended for small system where the benefits of the full
- * shmem code (swap-backed and resource-limited) are outweighed by
- * their complexity. On systems without swap this code should be
- * effectively equivalent, but much lighter weight.
