From 3bd1f4a173a3445f9919c21e775de2d8b9deacf8 Mon Sep 17 00:00:00 2001 From: Anton Altaparmakov Date: Sat, 25 Jun 2005 16:51:58 +0100 Subject: NTFS: Fix several occurences of a bug where we would perform 'var & ~const' with a 64-bit variable and a int, i.e. 32-bit, constant. This causes the higher order 32-bits of the 64-bit variable to be zeroed. To fix this cast the 'const' to the same 64-bit type as 'var'.
