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 > Date: Tue, 4 Oct 2011 11:04:09 -0700 > From: [email protected] > To: [email protected] > Subject: Re: How to open and write to a block driver within a character > driver? > CC: [email protected] > > On Tue, Oct 04, 2011 at 10:52:33AM -0700, Yang Xiang wrote: > > 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.
