New Revision: 219973
URL: http://svn.freebsd.org/changeset/base/219973

Log:
  Checking file access on size change is bogus. The checks are done earlier by
  VFS where we know if this is truncate(2) or ftruncate(2). If this is the
  latter we should depend on the mode the file was opened and not on the current
  permission.
