As noted by Chuck in the meantime, VFS_UNMOUNT() also flushes data (with the knowledge of wether this is a forced unmount or not), and nothing seems to prevent new dirty data to be added between the VFS_SYNC() and VFS_UNMOUNT(). This suggests the VFS_SYNC() just duplicates the flush operation, adding delay because it does not know about force unmount, and without any real benefit. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz m...@netbsd.org
