Subject: mds: use want_state to indicate shutdown
X-Git-Tag: v0.43~61
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ff5178c86a043a26ea8523dd5ac24462a8472fd4;p=ceph.git

mds: use want_state to indicate shutdown

State gets DNE when we receive the first map.  And want_ makes more sense
anyway.  Fixes MDS startup.
