Subject: librados: Added declaration for rados_aio_get_version
X-Git-Tag: v10.2.3~141^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=1c7abcbfe58f77d9d915dd2fc2fc4c75883d46c1;p=ceph.git

librados: Added declaration for rados_aio_get_version

Was missing from librados.h and hence had an incorrect
visability.

Fixes: #15535
(cherry picked from commit a5a1c1732e50be7d27f8742e794eba88d35c1c7f)
