From ece7d20e8be6730fbb29f4550de6b19b1a3a9387 Mon Sep 17 00:00:00 2001 From: Mike Fleetwood Date: Fri, 18 Nov 2011 18:55:01 +0000 Subject: [PATCH] Btrfs: Don't error on resizing FS to same size It seems overly harsh to fail a resize of a btrfs file system to the same size when a shrink or grow would succeed. User app GParted trips over this error. Allow it by bypassing the shrink or grow operation.
