Yes, silly me I got confused hunting down a strange problem in that area which
made me forget that volume special files are closed but the handles kept
around on purpose.
That problem, by they way, manifests itself as volume going offline, salvager
does not find anything, but volume going offline again. This time, the problem
is not a wrong magic in the link table which volinfo -fixheader would correct.
Usually, the users see messages like "unable to remove file - disk space
exceeded" - certainly a message to get confused.
It goes away if you move the volume to another server. i.e. the volume is ok.
It re-appears if you move the volume back to the *same* partition on the same
server. We found in the dumps that after the move ihandles for the volume
header stay around - this smells like a leak which made me jump on that patch
too quickly.
I'll engage brain before touching keyboard next time - sorry for that.

I believe the patch is correct. IH_REALLYCLOSE() will close the file
descriptors but not release the inode handle. Wherease IH_RELEASE()
will close the file descriptors and release the inode handle.
Likewise, VCloseVolumeHandles_r() is closing the file descriptors but
intentionally leaving the inode handles alone.
VReleaseVolumeHandles_r() is the equivalent function that is used to
release the inode handles.
