Odd coding style, please use kerneldoc format if you are going to have
comments like this.

+static inline int LZ4_compressBound(int isize) {
+  return LZ4_COMPRESSBOUND(isize);

And follow the proper kernel coding style rules, putting your patches
through scripts/checkpatch.pl should help you out here.

thanks,
