Description
This is a subset of the overall project to provide a way for client applications to reclaim state held by a previous instance of themselves. The initial phase of this project is to just allow a client application to cancel the MDS session held by a previous instance of itself.
The use case for this is NFS ganesha (and probably, eventually, Samba) which needs to have a way to kill off an old session in order to provide better failover response times. The pull request for this is here:
