From 0d882a360b9012bc7a7e921c935774c3fba1bfd9 Mon Sep 17 00:00:00 2001 From: Alain Renaud Date: Tue, 22 May 2012 15:56:21 -0500 Subject: Prefix IO_XX flags with XFS_IO_XX to avoid namespace colision. Add a XFS_ prefix to IO_DIRECT,XFS_IO_DELALLOC, XFS_IO_UNWRITTEN and XFS_IO_OVERWRITE. This to avoid namespace conflict with other modules.
