Kerenel module for character device, used to test in-kernel lzfse library.
Project Makefile expects kernel source tree to be in directory ../linux.
Also, patch that adds lzfse support should be applied.
To build module, run:
$ make
Then, module can be inserted as usual
# insmod lzfse_cdev.ko
Next, create two character devices, for example lzfse_encode and lzfse_decode.
Major number is 566, minor number for encoder is 0, for decoder is 1:
# mknod lzfse_encode c 566 0
# mknod lzfse_decode c 566 1
To compress data
$ cat file > lzfse_encode
$ cat lzfse_encode > file.lzfse
To decompress
$ cat file.lzfse > lzfse_decode
$ cat lzfse_decode > file
Be careful - data buffers have limited size and are shared between all created devices
