From 6d677e3504cd173b2ff7fc393ee4241b3c0f92a6 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 20 Apr 2007 16:12:40 -0400 Subject: [PATCH] NFS: Don't clear PG_writeback until after we've processed unstable writes Ensure that we don't release the PG_writeback lock until after the page has either been redirtied, or queued on the nfs_inode 'commit' list.
