From 094069f1d96f691637b5c335f5eb79566d2457ff Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 17 May 2016 12:28:43 -0400 Subject: [PATCH] flexfiles: remove pointless setting of NFS_LAYOUT_RETURN_REQUESTED Setting just the NFS_LAYOUT_RETURN_REQUESTED flag doesn't do anything, unless there are lsegs that are also being marked for return. At the point where that happens this flag is also set, so these set_bit calls don't do anything useful.
