New Revision: 240410
URL: http://svn.freebsd.org/changeset/base/240410

Log:
  Avoid mapping ENOENT to ENOTDIR for non-existent path components.
  
  The ENOTDIR mapping was introduced in r235266 for kern/128933 based on
  an interpretation of the somewhat ambiguous language in the POSIX realpath
  specification.  The interpretation is inconsistent with Solaris and Linux,
  a regression from 9.0, and does not appear to be permitted by the
  description of ENOTDIR:
  
       20 ENOTDIR Not a directory.  A component of the specified pathname
               existed, but it was not a directory, when a directory was
               expected.
