From 85c6201a80ce4464a52c58a5f5ea8de15a557a6f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 19 May 2010 14:06:29 +1000 Subject: [PATCH] crypto: scatterwalk - Fix scatterwalk_done() test We are done with the scattergather entry when the walk offset goes past sg->offset + sg->length, not when it crosses a page boundary. There is a similarly queer test in the second half of scatterwalk_pagedone() that probably needs some scrutiny. Signed-off-by: David S.
