[akpm]

The patch titled
     Subject: test_hexdump: check all bytes in real buffer
has been removed from the -mm tree.  Its filename was
     test_hexdump-check-all-bytes-in-real-buffer.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Subject: test_hexdump: check all bytes in real buffer

After processing by hex_dump_to_buffer() check all the parts to be expected.

Part 1. The actual expected hex dump with or without ASCII part.
	This is provided by plain strcmp() call including check for the
	terminating NUL.

Part 2. Check if the buffer is dirty beyond needed.
	We fill the buffer by ' ' (space) characters, so, we expect to have the
	tail of buffer will be left untouched. Check all bytes in the tail of
	the buffer.

Part 3. Return code should be as expected.
