Description :
Test 031 reproduces this one - it runs mkfs and then repairs
numerous different combinations of directory version and
directory size ... repair seems to get itself into trouble
without even mounting these filesystems (created using mkfs
prototype files).
To exercise this bug (use the sim mkfs/repair binaries, cos
we seem to trip an assert in libxfs-mkfs before completing):
$ cd cmd/xfs/sim
$ make
# make install
then running "./check 031" produces output along the lines...

Phase 3 - for each AG...
Phase 4 - check for duplicate blocks...
Phase 5 - rebuild AG headers and trees...
Phase 6 - check inode connectivity...
rebuilding directory inode 128
Phase 7 - verify and correct link counts...
