I've gotten in several hours of testing on this patch with
no issues at all, and no output from CONFIG_PROVE_LOCKING
(I'm assuming it would show up on a serial console).  So,
it seems to me this patch has done the trick.

CPU utilization is staying under control, and write-out rate
is good.

You can add my Tested-by: as you see fit.  If you work
up any refinements and would like me to test, please
let me know.

Thanks -- Jim
