From: Miklos Szeredi The patch titled "fuse: fix permission checking on sticky directories" removed all but the S_IFMT bits from i_mode. However some of these are unfortunately used by the VFS, such as the execute, suid and sgid bits. So only remove the sticky bit, which is used for checking deletion from a directory.
