Re: [PATCH] iommu/vt-d: constify intel_dma_ops.

[Arvind Yadav]

Hi,

Most dma_map_ops structures are never modified. Constify these
structures such that these can be write-protected. This file size diff
will show the difference between data and text segment.

Thanks,

What is the point of those commit-messages? They just show that the
struct moved from data to the text segment. The overall size doesn't
change much.
