e2fsprogs 1.41.7 (pu branch) basic sanity checks

I ran mkfs/e2fsck/mount/df on a 32-TB filesystem (built on LVM) with
the bits from the pu branch: no problems so far (other than
reporting problems - e.g. memory usage by e2fsck).

Here is the output:

$ sudo time mke2fs -q -t ext4 -O ^resize_inode -E stride=32,stripe-width=512 /dev/mapper/bigvg-bigvol
