------------------------------------------------

[WARNING]
/home/jenkins/jenkins-slave/workspace/PreCommit-HBASE-Build/hbase-common/src/main/java/org/apache/hadoop/hbase/util/ByteBuffUtils.java:38:
warning - @param argument "buffer" is not a parameter name.
{code}
This is the only javadoc warning now. In the last patch I did not change this
thinking it was pointing to BytebufferUtils and no such arg was there. My bad.
Will correct in follow up patch.

> In L2 cache (offheap) an HFile block might have been cached into multiple
> chunks of buffers. If HFileBlock need single BB, we will end up in recreation
> of bigger BB and copying. Instead we can make HFileBlock to serve data from
> an array of BBs.
