+Subject: [PATCH] safe_macros: make is_fuse() return zero if fs_type is NULL
+
+This commmit 28507e514c(safe_mount: Do not try mount() syscall for FUSE fs)
+involves FUSE fs check in safe_mount(), but we'd better guarantee the "fs_type"
+is legal to check in is_fuse() function otherwise system will kill the program.
