From 4dfb7cbef856689caebd0f498dbd140d1b79954f Mon Sep 17 00:00:00 2001 From: "Salyzyn, Mark" Date: Tue, 27 Mar 2007 15:07:28 -0400 Subject: [SCSI] aacraid: resolve compiler warnings using ptrdiff_t Unsigned long is not always the same size as a pointer, namely on 32 bit systems with 64 bit address space. Ptrdiff_t is the same size as a pointer in all configurations. By using ptrdiff_t we can mitigate the warning messages on these configurations. There should be no side effects of this patch.
