No vendor ever really shipped working support for this, and they are not interested in supporting it. With the NVMe support gone, we have nothing in the tree that supports this. Remove passing around of the hints. The only discussion point in this patchset imho is the fact that the file specific write hint setting/getting fcntl helpers will now return -1/EINVAL like they did before we supported write hints. No known applications use these functions, I only know of one prototype that I help do for RocksDB, and that's not used. That said, with a change like this, it's always a bit controversial. Alternatively, we could just make them return 0 and pretend it worked. It's placement based hints after all. Diffstat manually generated, as git pull-request doesn't like that it's based on merges. It will merge cleanly with your current tree. Please pull!
