: Hi,
: 
: I have this huge data structure in the data segment of my scsi driver.  This
: data structure is initialized at driver build time, and is used only during

: initialization.  I am trying to find out if I can free-up the memory it 
: occupies,
: once I am done with the driver initialization.  Does anyone know how to do 
: this?

Put it in a module, and unload the module.  Alternatively, load it
from userland.
