commit: c5c72d814cf0f650010337c73638b25e6d14d2d4 From: Theodore Ts'o <tytso@xxxxxxx> Date: Sun, 21 Apr 2013 20:19:43 -0400 Subject: 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.
