[SPDK] Re: Build failure for change https://review.spdk.io/gerrit/c/spdk/spdk/+/2140

Hi Wenhua Liu,

Looks like patch adding timestamps was introduced by Vitaliy very recently. Please see:
https://review.spdk.io/gerrit/c/spdk/spdk/+/2023

Going by the commit message, it looks like the rocksdb test depended on specific log output.

Thanks,
Tomek
