I would suggest vm_memory_committed() and there shouldn't be a comment describing that this is just a wrapper for modules to read vm_committed_as, that's apparent from the implementation: it should be describing exactly what this value represents and why it is a useful metric (at least in the case that you're concerned about). > With regards to making changes to the Xen self ballooning code, I would like > to separate that patch > from the patch that implements the exported mechanism to access the memory > commitment information. Why? Is xen using it for a different inference? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
