If anyone has any objections, please let me know. ------------------ From: Paulo Alcantara [ Upstream commit 6bd360447941357e959414a525aa62576a448116 ] Setting the file type in cf_mode without clearing the existing S_IFMT bits first is wrong as it corrupts the file type when cf_mode already has type bits set (e.g. S_IFREG | S_IFLNK == S_IFDIR | S_IFREG). Clear S_IFMT before setting S_IFLNK for native and SMB1 symlinks.
