Description

I am getting a number of these warnings during heavy disk I/O (such as
extracting a large tar, or even compiling from pkgsrc)

Oct 13 16:54:40 dfly kernel: conflict with vnode 0xd34cd600

The system continues to function properly as far as i can tell.

These can be ignored.  In fact, I will take out the warning now.
There was an inode-reuse race that was fixed a long time ago.  I added
the printf's to print out when the race would have occured if not for
the fix. This is the comment in the code:

/* * Check to see if an inode is in the hash table. This is used to interlock * file free operations to ensure that the vnode is not reused due to a * reallocate of its inode number before we have had a chance to recycle it.
*/

In anycase, just ignore it.
