But I'm confused about when we should add fixes tag. For example, The only purpose of this patch is to remove redundant macro definitions, the macros to be removed belong to 4 different former patches, so we have to add 4 lines of fixes. It seems difficult to merge this one back to previous versions of kernel. Should I split this patch into 4 patches and add a fixes tag for each one, or just put all these fixes tag in this patch? Thanks Weihang
