Hi Greg,

Let me rephrase my question then.

If I am in kernel space and in another device driver and I need to write a log entry of some sort to another block device, do I just perform an "open" and "write" as if I am in user space?

I am very new at this so bear with me on this.

Thanks in advance.
yx

The design is not up to me and I am just developing the code and I need to
develop the filter layer to convert the character buf to bio vects. But I am
wondering if there is a easy way to do this.

Then I suggest you push back on the design, just because someone told
you to do something incorrect, are you supposed to do it?

thanks,

greg k-h
