From 45b3947c2de5841d691f1d27d30419b9fae2d86c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 12 May 2008 11:55:10 +0800 Subject: [Blackfin] arch: Blackfin checksum annotations FSVOtest in this case, since I don't have the hardware... However, all changes seen by gcc are actually - explicit cast to unsigned short in return expression of functions returning unsigned short - csum_fold() return type changed from unsigned int to __sum16 (unsigned short), same as for all other architecture and as net/* expects; expression actually returned is ((~(sum << 16)) >> 16) with sum being unsigned 32bit, so it's (a) going to fit into the range of unsigned short and (b) had been unsigned all along, so no sign expansion mess happened.
