4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds torvalds@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.
