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

From: Matthew Wilcox <matthew@wil.cx>

buf[i] can be up to 0xfd, so doubling it and assigning the result to an
unsigned char truncates the value.  Just use an unsigned int instead;
it's only a temporary.
