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
