I was preparing for LSFMM and noticed that actually we're almost done with the writepage conversion. This patchset finishes it off. Something changed in my test environment and now it crashes before even starting a run, so this is only build tested. The first five patches (f2fs and vboxsf) are uninteresting. I'll try and get those into linux-next for the imminent merge window. I think the migrate and writeback patches are good, but maybe I've missed something. Then we come to i915 needing to tell shmem to do writeout, so I added a module-accessible function to do that. I also removed the setting/clearing of reclaim, which would be easy to bring back if it's really needed. Patch 10 is probably the exciting one where pageout() calls swap or shmem directly. And then patch 11 really just removes the op itself and the documentation for it. I may have over-trimmed here, but some of the documentation was so out of date it was hard to tell what was worth preserving. Anyway, let's see what the bots make of this. This is against next-20250307.
