VFS for Git virtual repositories are incompatible with FSMonitor. VFS for Git is a downstream fork of Git. It contains its own custom file system watcher that is aware of the virtualization. If a working directory is being managed by VFS for Git, we should not try to watch it because we may get incomplete results. We do not know anything about how VFS for Git works, but we do know that VFS for Git working directories contain a well-defined config setting. If it is set, mark the working directory as incompatible. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
