you made the same mistake here as on kernelnewbies.. you didn't post a

Subject: Expertise required:USB bulk-throughput and memory
leak detection


My team is developing a device driver for a PCMCIA based
USB device. We're currently trying to test the performance of
our driver. However we're unable to figure out a reliable methods of:
1.) detecting memory leaks caused by our driver code.
2.) Neither have we been able to find a tool which shows %
utilisation of kernel memory used by our driver.(kernel
memory monitoring)
3.) Throughput calculation of bulk data transfer is also not
precise. We still rely on measuring time on stop watch, while
Transferring data.

About the memory monitoring, there are quite a few tools
available at the application level (like free and top which
are available with the operating system itself). But none for
the kernel level.

Please suggest other feasible ways of detecting leaks and
monitoring kernel memory utilisation for kernel 2.6.15.4 on
fedora core 4.
