I want to do RAW I/O to a disk/partition from my ram disk driver. How I can achieve this? alloc_kiovec(..), map_user_kiobuf(...) and brw_kiovec(...) functions can be used for this? But these function map user space into kernel space memory, but in my driver I will be having only kernel space memory. Thanks in advance! Erforschen __________________________________ Do you Yahoo!?
