Subject: Trapping Block I/O
Date: Fri, 23 Sep 2005 18:13:14 +0530 [thread overview]
Message-ID: <64c7635405092305433356bd17@mail.gmail.com> (raw)
Hi,
I need to trap _all_ the I/O going to each and every block device
in the system. I used jprobes to trap calls to generic_make_request.
Is this the correct/only place to do such a thing ?
Or do I have to monitor the q->make_request_fn for every device ?
Thanks & Regards
-BD.
