[linux-mm-cc] rmzswap newbie question

[Vivek]

Hi,

When does a write or read happen from the rmzswap device? When does 
rmzswap_make_request function get called? If the kernel is built with 
rmzswap enabled then under what scenario does the system write and read 
to this device. Pls explain. I have gone through the code and am 
understanding it, the above or some of the questions that have come to 
my mind. Pointers to any doc are welcome.

Thank you,
Vivek S
