Hi Peter,

Sorry to bother, but now that the Linux merge window is closed could I
request a review of this revision of the ntsync patch set, please (or a
review from another locking maintainer)?

I believe I've addressed all of the comments from the last review,
except those which would have changed the existing userspace API
(although since the driver isn't really functional yet, maybe this
would have been fine to do anyway?)

Thanks,
Zeb
