Subject: [PATCH] FUSE: nfsd directory fsync fix
Date: Sun, 24 Apr 2005 17:26:45 +0200	[thread overview]
Message-ID: <E1DPj0P-0000NC-00@localhost> (raw)

This patch fixes an Oops which happens when nfsd calls fsync on a
directory with a NULL file argument.  The solution is to just ignore
the fsync.  Thanks to David Shaw for the bugreport.
