Hi! I want to share memory between two differents processes in kernel mode. The goal is to copy the read buffer of a user process into the read buffer of another user process. I know it's possible to do it by creating an intermediate buffer in kernel mode and to use the 'copy_from_memory' and 'copy_to_user' functions for copying data from a process to other, but this is a slow method. Can I do it in a different way? Are there functions for turning user space pointers into kernel space pointers without copying data? Thanks in advance, Rubén. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
