+ * Small amount of shim code needed to get zfs_zstd.c to compile. These items
+ * here should all be defined in the SPL or as part of libstand somewhere, but
+ * aren't for reasons that haven't been tracked down yet. Ideally, they would
+ * all go away and we'd compile zfs_zstd.c directly. Based on an original by
