This module marks all file in the share as offline. It can be useful for shares mounted on top of a remote file system (either through a samba VFS module or via FUSE). Offline files change the behavior of Windows explorer, and prevent it from peeking inside folders just for the sake of drawing a nice icon of them. This greatly reduces the number of requests Windows Explorer makes, and improves user experience when dealing with remote file systems. The offline bit also has an effect on the behavior of Windows redirector. Signed-off-by: Uri Simchoni <uri@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
