xfs_repair speedups

[Michael Guntsche]

Hi list,

I just tested the repair speedups on my setup here and could see a
big speed improvement.

The setup is an old Pentium IV 1.7GHz with 512MB RAM and a 1.2 TB XFS on
lvm2 on RAID-5.

time xfs_repair -n  Version 3.0.2

real    0m27.983s
user    0m20.641s
sys     0m4.436s


time xfs_repair -n  Version 3.0.3-repair-speedups

real    0m8.599s
user    0m2.444s
sys     0m0.228s


Especially Phase 4 is a lot faster on my setup here.

Kind regards,
     Michael
