<br>
I would like to monitor the write access to disk blocks (so that I can<br>
monitor the block index in some bitmap)<br>
I think this must be done in kernel (userspace have no such information)<br>
I have tried to search in kernel but did not found where is the API to<br>
access disk blocks.<br>
There is libata-core.c , but I can't find such routines there, and<br>
neither any documentation.<br>
<br>
Is there any idea ?<br>
<br>
Regards,<br>
