Memory profiling tools for Linux Kernel

[Kumar Amit Mehta]

I was looking for some tools for memory profiling for Linux Kernel. I
I wish to analyze the memory usage statistics by comparing the results
(with and without the usage of Lookaside caches) by the consumer (Say
a certain driver).I found some tools such as kmemcheck[1] and KEDR [2]
but before I go further and explore these tools, I was wondering if
somebody has already used these tools to acquire similar statistics
or I should try out some other tool.
