So I thought I'd give people an update on what's been happening on the
e2fsprogs 64-bit patch queue. I've done a lot of work to make the
patches easier to understand, including fixing bugs in the patches in
relevant patch in the patch queue, instead of as follow on patches.
So a number of Nick's patches have been folded into the patch which
introduced the bug in the first place. This makes it easier to clean
up the patches, and it also makes it easier to find problems by code
inspection. For example, a number of missing blk64_t conversions were
found by taking Nick's patches, applying them to patch #15,
0015-Convert-to-inode-block-bitmap-table-loc-loc_set.patch, and then
seeing if there were any similar omissions mades in that patch.
So the git log on the e2fsprogs 64-bit patch queue shows a fair amount
of church, including shrinking the e2fsprogs patch queue by 9 patches:

Add .gitignore file.
However, the actual changes between the previous pu branch and the
latest one is *much* smaller. (The patch does include some pretty
significant patch fixes, including one that would cause e2fsck blow up
if used on a > 32-bit filesystem where any of the inodes located in
the part of the filesystem where the block number is > 2**32.)
The bottom line is the patches still need a fair amount of auditing,
cleanup, and testing, but progress is being made, slowly....
