Subject: ceph: close old con before reopening on mds reconnect
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a53aab645c82f0146e35684b34692c69b5118121;p=openwrt%2Fstaging%2Fblogic.git

ceph: close old con before reopening on mds reconnect

When we detect a mds session reset, close the old ceph_connection before
reopening it.  This ensures we clean up the old socket properly and keep
the ceph_connection state correct.
