137 and the file named by

141 The directory in which the entry for the new link is being placed
142 cannot be extended because there is no space left on the file
143 system containing the directory.
145 The directory in which the entry for the new link
146 is being placed cannot be extended because the
147 user's quota of disk blocks on the file system
148 containing the directory has been exhausted.
