-> 95 is EOPNOTSUPP

http://man7.org/linux/man-pages/man2/fallocate.2.html
-> fallocate can indeed return EOPNOTSUPP if:
  "The filesystem containing the file referred to by fd does not support this operation;
   or the mode is not supported by the filesystem containing the file referred to by fd."
 
filesystem = ext3
