From 3976143b063e3c42fe5471d87860f6ae118e0eee Mon Sep 17 00:00:00 2001 From: Peng Tao Date: Fri, 21 Aug 2015 12:49:44 +0800 Subject: NFS41: remove NFS_LAYOUT_ROC flag If we return delegation before closing, we fail to do roc check during close because NFS_LAYOUT_ROC is cleared by delegreturn and it causes layouts to be still hanging around after delegreturn + close, which is a voilation against protocol.
