mfsymlinks support for SMB2.1/SMB3. Part 2 query symlink
Adds support on SMB2.1 and SMB3 mounts for emulation of symlinks via the "Minshall/French" symlink format already used for cifs mounts when mfsymlinks mount option is used (and also used by Apple). http://wiki.samba.org/index.php/UNIX_Extensions#Minshall.2BFrench_symlinks This second patch adds support to query them (recognize them as symlinks and read them). Third version of patch makes minor corrections to error handling. Signed-off-by: Steve French <smfrench@gmail.com> Reviewed-by: Stefan Metzmacher <metze@samba.org>
