I just checked again and see that Allen's patch addresses the first two
of my three patches, but he picked a different approach for
transaction_kthread(): My patch moved to CLOCK_MONOTONIC,
while his version only changed the to time64_t but kept the
CLOCK_REALTIME behavior. It's a small difference, but I think
my version is slightly better. My patch 2/3 is identical to his version.

If you like, I can also rebase my patch 1/3 on top of his patch and
change it to CLOCK_MONOTONIC.
