Here's the current relay cleanup patchset.
1-2 make the write path completely replaceable. 3 adds flags along with some related cleanup. 4-8 remove the padding in several stages.
The new patches in this set are:
9 simplifies the callbacks - now that we have flags, the subbuf_start callback is much simpler, has been combined with notify_consumers and has been renamed new_subbuf. Because part of the simplification has been to handle buffer-full conditions and count lost events internally, normal applications don't have to pay attention to it at all.
10 completely removes the idea of sub-buffers completely and now deals only with pages. relay_open() channges accordingly - buffer sizes are now in pages and consumers are woken only every n_wakeup pages, or never if this is 0.
It's a work in progress, but because I wanted the intermediate stages to actually work and not break anything, some of these patches, especially 05, are just temporary and will be removed in the next iteration.
I didn't have time to clean up the first 3 either - I'll also do that the next time around.
In the next round I plan to do vmap removal.
Tom
