Subject: rgw/lc: random_sequence() uses default_random_engine
X-Git-Tag: v18.0.0~306^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=60f5664761b7419d82cc4f92ff11d1bcfbd13716;p=ceph.git

rgw/lc: random_sequence() uses default_random_engine

we used random_device to seed a default_random_engine, but didn't use
the engine in our call to shuffle()
