From b381beadee8a3d6e690d30bdccddd08ab024945e Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 30 Jan 2006 08:47:14 +0000 Subject: [GFS2] Remove unused file resize.c The code in this file is no longer used as the rindex file is now accessible to userspace, so can be read/written directly.
