[PATCH v2 manager 0/1] fix #7518: ceph: mon: advertise a single address per monitor

[Kefu Chai <k.chai@proxmox.com>]

pveceph mon create can put two addresses of the same messenger type
into a monitor's addrvec. Older kernels refuse to decode that, so
CephFS fails to mount. This makes it pick one address per monitor.

The kernel side is fixed in the meantime, so v2 only rewords the
commit message. The code is unchanged.

Changes since v1:
 - say that current kernels tolerate such addrvecs since 5a87925539ac
   ("libceph: tolerate addrvecs with multiple entries of the same
   type"), which went to stable, and that the reasons to still pick a
   single address are older kernels and that no client reads past the
   first match
 - no code change
