Message-Id: <1366589162-28527-1-git-send-email-tytso@mit.edu> Date: Sun, 21 Apr 2013 20:06:02 -0400 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Cc: sandeen@...hat.com, Theodore Ts'o <tytso@....edu> Subject: [PATCH] ext4: fix online resizing for ext3-compat file systems Commit fb0a387dcdc restricts block allocations for indirect-mapped files to block groups less than s_blockfile_groups. However, the online resizing code wasn't setting s_blockfile_groups, so the newly added block groups were not available for non-extent mapped files.
