From dfa159886f38344ede31e3b13ec614e0bebc09c6 Mon Sep 17 00:00:00 2001 From: Mark Lord Date: Mon, 12 Dec 2005 23:19:28 -0500 Subject: [PATCH] [PATCH] libata-core.c: fix parameter bug on kunmap_atomic() calls Fix incorrect pointer usage on two calls to kunmap_atomic(). This seems to happen a lot, because kunmap() wants the struct page *, whereas kunmap_atomic() instead wants the mapped virtual address.
