Submit #2764: [PATCH] sys/vfs/hammer: fix comments regarding obsolete "spike" code

* Author: tkusumi
* Status: New
* Priority: Normal
* Assignee: 
* Category: VFS subsystem
* Target version: 
This patch fixes comments regarding "spike" code that only existed in early days of hammer development. The spike comments have been left unchanged even after the code was removed in 47197d71536907482d2d215e222600eed3aedc0e.
This patch is kernel cleanup in addition to userspace cleanup http://bugs.dragonflybsd.org/issues/2761. These two patches get rid of spike code at least in grep level.
