Yeah we use Fixes: a lot, also to help all our product teams, who have all varying versions of frankenstein kernels. If they cherry-pick some feature from upstream, they need to know which bugfixes to backport. cc: stable is orthogonal to Fixes:, but Fixes should imo indicate a real bugfix (i.e. if you have the first patch, you want all the patches with Fixes: lines referencing that patch). Unfortunately on the mobile/gfx side there's very few customers who just use a stable release, so we need to be rather dutiful with sprinkling Fixes: tags over everything that fixes bugs (but not more, otherwise there's screaming about backporting too much). -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch
