Subject[PATCH] ceph: downgrade warning from mdsmap decode to debug
Date
While the MDS cluster is unstable and changing state the client may get
mdsmap updates that will trigger warnings:

[144692.478400] ceph: mdsmap_decode got incorrect state(up:standby-replay)
[144697.489552] ceph: mdsmap_decode got incorrect state(up:standby-replay)
[144697.489580] ceph: mdsmap_decode got incorrect state(up:standby-replay)

This patch downgrades these warnings to debug, as they may flood the logs
if the cluster is unstable for a while.

Hi!

This patch follows from my other patch "ceph: fix race in concurrent
__ceph_remove_cap invocations", where I see a *lot* of warnings before the
NULL pointer. Maybe this could be a pr_warn_once instead, but not sure
that would be useful.

Note that before commit 4d7ace02ba5c ("ceph: fix mdsmap cluster available
check based on laggy number") this was simply ignored without any pr_warn
or dout.

Cheers,
