Use devm_ioremap_resource instead of reques_mem_region()/ioremap() and
devm_request_irq() instead of request_irq().
This ensures more consistent error values and simplifies error paths.

liblockdep is a tiny wrapper built around kernel/lockdep.c. The aim is to
provide the same functionality the kernel gets from lockdep to userspace.
The bulk of the code here is the LD_PRELOAD support which provides users
an easy way to test their code without having to integrate liblockdep into
sa
A simple test to make sure we handle rwlocks correctly.

All we need is to wrap two functions which are used by lockdep

obvious. What does the timehist command do, btw? ;)
