Hi Zheng,
There should be an explanation in the commit message of what this is
and why it is needed.
I'm assuming the use case is recovering a blacklisted mount, but what
is the intended semantics? What happens to in-flight OSD requests,
MDS requests, open files, etc? These are things that should really be
written down.
Looking at the previous patch, it appears that in-flight OSD requests
are simply retried, as they would be on a regular connection fault. Is
that safe?
Thanks,
Ilya
