|
|
*
|
|
* - 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.
