Under normal circumstances, there shouldn't be any noticeable difference
in performance. If there are a lot of zero link count files, phase 1
should be very slightly faster because the zero link count file list no
longer needs to be allocated, and phase 4 should be a lot faster. Most
of the time in phases 1 and 2 is consumed by disk reads. The only
change to phase 2 was the addition of the new inode states to a couple
of case statements and an if statement which should not affect the
amount of I/O done and CPU time would only be affected by a miniscule
amount, so I would not expect any change to the performance of that
phase.
