Message-Id: <1398694179-18027-2-git-send-email-tytso@mit.edu> Date: Mon, 28 Apr 2014 10:09:39 -0400 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Cc: Theodore Ts'o <tytso@....edu> Subject: [PATCH 2/2] resize2fs: fix inode table move for the backwards move case In the case where the new location of the inode table is before the old inode table, the optimization which tries to optimize zero block moves breaks. Fix it. This fixes a bug that was tickled by the reproduction described in the previous commit.
