From 7211a4e859ad070b28545c06e0a6cb60b3b8aa31 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 25 Dec 2009 17:44:45 +0100 Subject: [PATCH] nfsd: make sure data is on disk before calling ->fsync nfsd is not using vfs_fsync, so I missed it when changing the calling convention during the 2.6.32 window. This patch fixes it to not only start the data writeout, but also wait for it to complete before calling into ->fsync. Signed-off-by: Christoph Hellwig Cc: stable@kernel.org Signed-off-by: J.
