If anyone has any objections, please let me know. ------------------ From: Paulo Alcantara commit fa7a2cfcf1e6117fc478cae6809c66c518740969 upstream. 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_IFCHR == S_IFLNK). Clear S_IFMT before the switch statement.
