  "message": "NFSv4: Fix a potential state manager deadlock when returning delegations\n\nThe nfsv4 state manager could potentially deadlock inside\n__nfs_inode_return_delegation() if the server reboots, so that the calls to\nnfs_msync_inode() end up waiting on state recovery to complete.\n\nAlso ensure that if a server reboot or network partition causes us to have\nto stop returning delegations, that NFS4CLNT_DELEGRETURN is set so that\nthe state manager can resume any outstanding delegation returns after it\nhas dealt with the state recovery situation.\n\nFinally, ensure that the state manager doesn\u0027t wait for the DELEGRETURN\ncall to complete. It doesn\u0027t need to, and that too can cause a deadlock.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n",
