Subject: cephsqlite: hide non-public symbols
X-Git-Tag: v17.1.0~2473^2~2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=21486ed9531506362465300512617b2838780a1c;p=ceph-ci.git

cephsqlite: hide non-public symbols

mark public interfaces using `[[gnu::visibility("default")]]`, so
we can expose them when the default visibility is "hidden".
