Revert "NFS: Ensure that writeback_single_inode() calls write_inode() when syncing" commit 59b7c05fffba030e5d9e72324691e2f99aa69b79 upstream. This reverts commit b80c3cb628f0ebc241b02e38dd028969fb8026a2. The reverted commit was rendered obsolete by a VFS fix: commit 5547e8aac6f71505d621a612de2fca0dd988b439 (writeback: Update dirty flags in two steps). We now no longer need to worry about writeback_single_inode() missing our marking the inode for COMMIT in 'do_writepages()' call. Reverting this patch, fixes a performance regression in which the inode would continuously get queued to the dirty list, causing the writeback code to unnecessarily try to send a COMMIT.
