Subject: AsyncConnection: dispatch write handler on keepalive2
X-Git-Tag: v11.1.0~351^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F11601%2Fhead;p=ceph.git

AsyncConnection: dispatch write handler on keepalive2

...otherwise, if the connection is idle (i.e. no proper TAG_MSG
messages), keepalive ack will not get sent until some point in the
future.

Fixes: #17664
