/* Always create files using a NULL SD. Create correct permission bits
afterwards, maintaining the owner and group information just like chmod.
This is done for two reasons.
On Windows filesystems we need to create the file with default
permissions to allow inheriting ACEs. When providing an explicit DACL
in calls to [Nt]CreateFile, the created file will not inherit default
permissions from the parent object. This breaks not only Windows
inheritance, but also POSIX ACL inheritance.
Another reason to do this are remote shares. Files on a remote share
are created as the user used for authentication. In a domain that's
usually the user you're logged in as. Outside of a domain you're
authenticating using a local user account on the sharing machine.
If the SIDs of the client machine are used, that's entirely
unexpected behaviour. Doing it like we do here creates the expected SD
in a domain as well as on standalone servers.
This is the result of a discussion on the samba-technical list, starting at
http://lists.samba.org/archive/samba-technical/2008-July/060247.html */

Change the way open_fs is called. Explain why. (fhandler_base::fstat_helper): Use handle returned by get_stat_handle. Never use 0 inode number.
