From: Trond Myklebust <trond.myklebust@hammerspace.com> stable inclusion from linux-4.19.169 commit 87396ce3b5059916e81b6c3456a5c2b9b7636b5f -------------------------------- commit 67bbceedc9bb8ad48993a8bd6486054756d711f4 upstream. If the layout return-on-close failed because the layoutreturn was never sent, then we should mark the layout for return again.
