      ceph: fix multiple mds session shutdown · f3c60c59
      Sage Weil authored
      
      
      The use of a completion when waiting for session shutdown during umount is
      inappropriate, given the complexity of the condition.  For multiple MDS's,
      this resulted in the umount thread spinning, often preventing the session
      close message from being processed in some cases.
      
      Switch to a waitqueue and defined a condition helper.  This cleans things
      up nicely.

      ceph: only queue async writeback on cap revocation if there is dirty data · 0eb6cd49
      Sage Weil authored
      
      
      Normally, if the Fb cap bit is being revoked, we queue an async writeback.
      If there is no dirty data but we still hold the cap, this leaves the
      client sitting around doing nothing until the cap timeouts expire and the
      cap is released on its own (as it would have been without the revocation).
      
      Instead, only queue writeback if the bit is actually used (i.e., we have
      dirty data).  If not, we can reply to the revocation immediately.
