Ok, second version of the evdev buffer patches. In the first patch, the locking has been completely reworked. The buffer locking is now similar to seqlock, except the readers only block while there is an update affecting the current read. Should be fairly optimal, but we can always revert to seqlocks in case the scatter of smp instructions feels inadequate. The second patch only has trivial changes, and the third patch is unchanged, but included for completeness.
