Hi all,
Here's the respin. Changes:
- 2 patches for checking return values of callbacks dropped, they landed
- move the lockdep annotations ahead, since I think that part is less contentious. lockdep map now also annotates invalidate_range_end, as requested by Jason.
- add a patch to prime lockdep, idea from Jason, let's hear whether the implementation fits.
- I've stuck with the non_block_start/end for now and not switched back to preempt_disable/enable, but with comments as suggested by Andrew. Hopefully that fits the bill, otherwise I can go back again if the consensus is more there.
Review, comments and ideas very much welcome.
Cheers, Daniel
