At least in theory.  In practise, it's not usable because:

The underlying problem is that there are 2 zlib's in the kernel tree.
One is in sys/cddl/contrib/opensolaris/uts/common/zmod/ and the other
is sys/net/zlib.c.  The real fix is to get rid of one of them and use
the remaining one for all subsystems that want zlib.  I agree that
merging them is non-trivial because they are based on different
versions of zlib (1.2.3 & 1.0.4, respectively) and the original files
have been munged is different ways.  (And there's a third inflate(9)
based on unzip-5.12 in sys/kern/inflate.c, as well as another complete
zlib-1.2.7 in lib/libz)
