Subject: libceph: use CEPH_MON_PORT when the specified port is 0
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f48db1e9ac6f1578ab7efef9f66c70279e2f0cb5;p=deliverable%2Flinux.git

libceph: use CEPH_MON_PORT when the specified port is 0

Similar to userspace, don't bail with "parse_ips bad ip ..." if the
specified port is port 0, instead use port CEPH_MON_PORT (6789, the
default monitor port).
