From c22870ea2deb2841402133909cfa707a2c0b12ed Mon Sep 17 00:00:00 2001 From: Steve French Date: Tue, 16 Sep 2014 07:18:19 -0500 Subject: 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.
