Hi,
I recently came across this tool called KEDR[1] for checking memory leak in kernel modules. I'm using it to check If my trivial kernel modules (based on LDD3 examples) are leaking memory. I was wondering if there exist a similar tool for checking incorrect usage of locking techniques implemented by kernel module.
You can make use of the in-kernel "lockdep" framework to check your locking. Just enable it in your .config, and build and boot your kernel. Lockdep detects a variety of locking problems at run time and warns you if there is a possibility of deadlock etc. Regards, Srivatsa S. Bhat
