Subject: [166/200] nfsd: nfsd_setattr needs to call commit_metadata

2.6.34-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Hellwig <hch@....de>

commit b160fdabe93a8a53094f90f02bf4dcb500782aab upstream.

The conversion of write_inode_now calls to commit_metadata in commit
f501912a35c02eadc55ca9396ece55fe36f785d0 missed out the call in nfsd_setattr.

But without this conversion we can't guarantee that a SETATTR request
has actually been commited to disk with XFS, which causes a regression
from 2.6.32 (only for NFSv2, but anyway).
