The logic for handling 64-bit structure elements was reversed, which
caused attempts to set fields like kbytes_written to fail:
% debugfs -w /tmp/foo.img
debugfs 1.45.6 (20-Mar-2020)
debugfs: set_super_value kbytes_written 1024
64-bit field kbytes_written has a second 64-bit field
defined; BUG?!?

Define MKDIR_P in the Makefile.in files instead in MCONFIG.in
In the case where mkdir -p is not thread-safe (for example, if the
build environment is using busybox's mkdir) the configure script will
fall back to the slow (but safe) install-sh script. In that case
MKDIR_P will be using a relative pathname; so we can't use speed
optimization of defining configure substitutions in MCONFIG.in, since
the substitution will be different depending on depth of the
subdirectory in the Makefile.in file.

resize2fs: prevent block group descriptors from overflowing the first bg
For 1k block file systems, resizing a file system larger than 1073610752 blocks will result in the size of the block group
descriptors to be so large that it will overlap with the backup
superblock in block group #1. This problem can be reproduced via:
Since commit [382ed4a1 e2fsck: use proper types for variables][1]
applied, it used ext2_ino_t instead of ino_t for referencing inode
numbers, but the type of is_hardlink's `ino' should not be instead,
The ext2_ino_t is 32bit, if inode > 0xFFFFFFFF, its value will be
truncated.
Add a debug printf to show the value of inode, when it check for hardlink
files, it will always return false if inode > 0xFFFFFFFF

mke2fs: Warn if fs block size is incompatible with DAX
If we are creating filesystem on DAX capable device, warn if set block
size is incompatible with DAX to give admin some hint why DAX might not
be available.
