compression tests in jffs2

[Matías Zabaljáuregui]

yes, I know... thank you for the advice.

In compr.c file, I can see some "stats" and "compression-mode" getters  
and setters, between  CONFIG_JFFS2_PROC  #ifdef and #endif... Do you  
think it is posible to reuse this code for implementing a sysfs  
interface?
