Subject: test_keyvaluedb_iterators.cc: use empty() to check for emptiness
X-Git-Tag: v0.58~66^2~9
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=e551dd4c5d6dd72d10dd5d3dc6e7388ab0704ff1;p=ceph.git

test_keyvaluedb_iterators.cc: use empty() to check for emptiness

Use !empty() instead of 'size() > 0' to check for emptiness for
performance reasons.
