Revision d25e28d584d20650127cde9b1ea66c41eaf187f2 authored by Nikhil Benesch on 03 April 2017, 18:19:29 UTC, committed by Facebook Github Bot on 03 April 2017, 18:39:09 UTC
Summary: `uint` is nonstandard and not a built-in type on all compilers; replace it with the always-valid `unsigned int`. I assume this went unnoticed because it's inside an `#ifdef ROCKDB_JEMALLOC`. Closes https://github.com/facebook/rocksdb/pull/2075 Differential Revision: D4820427 Pulled By: ajkr fbshipit-source-id: 0876561
