3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Theodore Ts'o <tytso@mit.edu>
commit c5c72d814cf0f650010337c73638b25e6d14d2d4 upstream.
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.
