Building module/zfs/dbuf.c for 32-bit targets can result in a warning:
In file included from
/usr/src/sys/contrib/openzfs/include/sys/zfs_context.h:97,

| ^~~~~~~
This is because dbuf_find_dirty_eq() returns a pointer, which if
pointers are 32-bit results in a warning about the cast to uint64_t.
Instead, use the ASSERT3P() macro, with == and NULL as second and third
arguments, which should work regardless of the target's bitness.
