The change is OK, but the commit message is confusing: I thought this would be mangling with the debug_mds log level. Something like "log at a lower level when stopping" would be more appropriate IMO.

[vshankar]

Minor commit message change - otherwise LGTM.

Looks good!

Commit message can take minor improvement -

Log at a lower level when the MDS is going to stop so that issues like
MDS becoming laggy can be tracked down. Reduce the log level from 7 to 5.

If you could add a bit more context from BZ in ticket description and in commit message, it would be useful in future.

I'll pick this PR in testing as soon as last couple of PRs from current batch get merged.

I think this change is good to merge (I've been lenient on dout() related changes to speed up merges).

@rishabh-d-dave If you are fine with it, I'll merge this (if its in your test branch, its probably fine)?
