Subject: rest_bench.cc: use empty() to check for emptiness
X-Git-Tag: v0.58~66^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ab1166cd9cc140b0ea63139af55ad809e9d9b4ab;p=ceph.git

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

Use empty() instead of 'size() == 0' or 'size() < 1' to check
for emptiness for performance reasons.
