[PATCH next 0/8] test_hexdump: Improve test coverage

[David Laight <david.laight.linux@gmail.com>]

It was suggested that I add some addition tests for hex_dump_to_buffer().
This required reworking the test code so that could verify arbitrary data.

16 of the tests (those with zero len and bufsize) fail on the current
kernel (the return value should be zero but is ascii ? 3 * rowsize : -1)

There are now 2000 tests that include more buffer overflow conditions and
all 256 bytes values.

David Laight (8):
  Change rowsize and groupsize to size_t
  Create test output data from the binary input data buffer
  Use longer variable names
  Check for buffer overrun of sample output buffer
  Fix sample output if zero bytes requested
  If a test fails print all the parameters
  Run fixed not random tests
  Test all 256 byte values
