[PATCH 4.19 02/41] test_hexdump: use memcpy instead of strncpy

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Linus Torvalds <torva...@linux-foundation.org>

commit b1286ed7158e9b62787508066283ab0b8850b518 upstream.

New versions of gcc reasonably warn about the odd pattern of

        strncpy(p, q, strlen(q));

which really doesn't make sense: the strncpy() ends up being just a slow
and odd way to write memcpy() in this case.

Apparently there was a patch for this floating around earlier, but it
got lost.
