The following two patches were sufficient for me to resize a test file
system from 14 TB to 18 TB.  We still need to handle automatic
enabling of the meta_bg flag in resize2fs, but this should be
sufficient for more adventurous folks to test the online resize
patches.  (Note that I also posted a v2 version of patch 5/5 which
fixed a number of 64-bit overflow bugs that I found in my testing.)
