If anyone has any objections, please let me know. ------------------ From: Sage Weil (cherry picked from commit 735a72ef952d42a256f79ae3e6dc1c17a45c041b) Do not re-initialize the con on every connection attempt. When we ceph_con_close, there may still be work queued on the socket (e.g., to close it), and re-initializing will clobber the work_struct state.
