Is there still value in testing your last patch?
The result should be the same, so it's not really necessary. But,
just in case, sticking that patch when you test the barrier would be
nice so that things can be verified again.
I applied both patches and rebooted - many minutes later & 94MB of log
file, I ran my synchronous file write test (the last 200 lines of the
log file is attached). Is more useful?
Thanks for testing.
thanks for the code - this is great!
