Re: UNDO with FILEOPS, and the FLUX table AM

Thanks, the fixes you describe are what I hoped for, and I was about to
measure them. But I think the wrong tarball went out: undo-v6.tar.gz is v3
with a new version number. Diffing each v6-00NN against v3-00NN, the only
line that differs in all 20 files is the "[PATCH v6 NN/20]" in the Subject;
the commit ids in the "From <sha>" lines are v3's (0001 is b7667c1ca7bf).
There is no cover letter, no test_fileops/t/017, slog_num_partitions is still
in 0005, and 0004 still adds 073-075 etc. It also lacks v4's record
alignment fix, so cfbot will be testing v3 again.

Could you resend the real v6? I'll run 017 on the three paths, the chmod
repro against v4 on the same machine, and the per-prefix check as soon as it
is out.

Regards,
Manu
