From 67911c8f18b595040f5c2df0550c69a7c9397891 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Tue, 19 Jan 2016 14:37:30 -0500 Subject: NFS: Add nfs_commit_file() Copy will use this to set up a commit request for a generic range. I don't want to allocate a new pagecache entry for the file, so I needed to change parts of the commit path to handle requests with a null wb_page.
