*	mm: cma: allocation trigger	Sasha Levin	2015-04-14	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Provides a userspace interface to trigger a CMA allocation. Usage: echo [pages] > alloc This would provide testing/fuzzing access to the CMA allocation paths.

*	mm: cma: debugfs interface	Sasha Levin	2015-04-14	1	-0/+20
	I've noticed that there is no interfaces exposed by CMA which would let me fuzz what's going on in there. This small patchset exposes some information out to userspace, plus adds the ability to trigger allocation and freeing from userspace. This patch (of 3): Implement a simple debugfs interface to expose information about CMA areas in the system. Useful for testing/sanity checks for CMA since it was impossible to previously retrieve this information in userspace.
