- * uncompress.c
- *
- * (C) Copyright 1999 Linus Torvalds
- *
- * cramfs interfaces to the uncompression library. There's really just
- * three entrypoints:
- *
- *  - cramfs_uncompress_init() - called to initialize the thing.
- *  - cramfs_uncompress_exit() - tell me when you're done
- *  - cramfs_uncompress_block() - uncompress a block.
- *
- * NOTE NOTE NOTE! The uncompression is entirely single-threaded. We
- * only have one stream, and we'll initialize it only once even if it
- * then is used by multiple filesystems.
