Author: rmacklem Date: Tue Jan 3 04:12:40 2012 New Revision: 229365 URL: http://svn.freebsd.org/changeset/base/229365 Log: MFC: r227543 Modify the new NFS client so that nfs_fsync() only calls ncl_flush() for regular files. Since other file types don't write into the buffer cache, calling ncl_flush() is almost a no-op. However, it does clear the NMODIFIED flag and this shouldn't be done by nfs_fsync() for directories.
