[PATCH v1 0/2] hw/vfio: Improve vfio_get_dirty_bitmap() tracepoint

[Joao Martins <joao.m.martins@oracle.com>]

Hey,

This tiny series changes the tracepoint to include the number of
dirty pages via the vfio_get_dirty_bitmap. I find it useful for
observability in general to understand the number of dirty pages in an
IOVA range. With dirty tracking supported by device or IOMMU it's specially
relevant data to include in the tracepoint.

First patch includes the dirty argument in the helper function setting
dirty bits and the second patch just expands the tracepoint to include
the dirty pages.

Thanks,
	Joao
