Subject: common: ceph_argparse_witharg: pass oss by reference
X-Git-Tag: v9.0.0~16^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c579ebfebb5132e230c661dfb121778a4e0b9e2c;p=ceph.git

common: ceph_argparse_witharg: pass oss by reference

It is always supposed to be a valid pointer here.
