[PATCH] generic: drop test 472

[PATCH] generic: drop test 472

[Theodore Ts'o]

>From Goldwyn Rodrigues <rgoldwyn@suse.de>:

   "From earlier discussions, In between errors of a direct I/O cannot
   be handled correctly and may need a lot of tracking that it is not
   worth performing.

   It would be better to drop this test case and add in the documentation
   that a direct I/O error could mean that the write() may or may not have
   occurred and underlying data may be inconsistent."

-# write() to a file opened with O_DIRECT with count > remaining

-# showing no data is written, but the file contents are updated.
-# Result should be the write should return remaining bytes
-# (to aligned bytes) instead of ENOSPC error.
