[dm-devel] Possible data corruption with dm-thin

[Dennis Yang]

Hi Joe,

Sorry for the late reply. We have been fixing bugs and conducting many
experiments with heavy I/O to verify the correctness and stability of our
storage. This problem I mentioned in this thread cannot be reproduced
anymore with these two patches (I applied them back to 3.19.8 and 4.2.8 and
both work fine).

Thanks for your help.

Dennis
