Hi all, Where can I find information about device mappers ?? Regarding dm_table,dm_dev, dm_target. I am having a look into the code, But I am not able to understand the dependencies between the various structures and the function calls defined. I read about LVM as well, but it doesnt talk about its underlying mechanism. Kindly help. -- Regards, Sandeep Winners expect to win in advance.
