blkid_dev_has_tag() will immediately return -1 (an error if value is
NULL. Thus at the test later on value cannot be NULL. There are two
possible ways to go about fixing this. The first would be to remove the
first NULL check for value. The second one would be to remove the
second check (and the deadcode).
I chose the second path because the functionality added is something
which a programmer could reasonably expect given the function name, and
it is highly unlikely any existing code is depending on the fact that
blkid_dev_has_tag() will return an error if value is NULL.

Add directory hashed signed/unsigned hint to superblock
The e2fsprogs and kernel implementation of directory hash tree has a
bug which causes the implementation to be dependent on whether
characters are signed or unsigned. Platforms such as the PowerPC,
Arm, and S/390 have signed characters by default, which means that
hash directories on those systems are incompatible with hash
directories on other systems, such as the x86.
To fix this we add a new flags field to the superblock, and define two
new bits in that field to indicate whether or not the directory should
be signed or unsigned. If the bits are not set, e2fsck and fixed
kernels will set them to the signed/unsigned value of the currently
running platform, and then respect those bits when calculating the
directory hash. This allows compatibility with current filesystems,
as well as allowing cross-architectural compatibility.
