Hi Zorro,
Instead of forking 23,000+ lines of MAINTAINERS and 2600+ lines of
script into a strange tools/ location ("tools/" would then mean fstests,
and "scripts/" would mean "everything else), this upgrade really should
simply be done in place.
I don't see much in the following patches that *truly* requires forking
these files. And if you fix them up in place, then more people will be
able to find the fstests maintainers easily, too.
thanks,

> +Notes:
> + Using "-f directory" may give unexpected results:
> + Used with "--git", git signators for _all_ files in and below
> + directory are examined as git recurses directories.
> + Any specified X: (exclude) pattern matches are _not_ ignored.
> + Used with "--nogit", directory is used as a pattern match,
> + no individual file within the directory or subdirectory
> + is matched.
> + Used with "--git-blame", does not iterate all files in directory
> + Using "--git-blame" is slow and may add old committers and authors
> + that are no longer active maintainers to the output.
> + Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
> + other automated tools that expect only ["name"] <email address>
> + may not work because of additional output after <email address>.
> + Using "--rolestats" and "--git-blame" shows the #/total=% commits,
> + not the percentage of the entire file authored. # of commits is
> + not a good measure of amount of code authored. 1 major commit may
> + contain a thousand lines, 5 trivial commits may modify a single line.
> + If git is not installed, but mercurial (hg) is installed and an .hg
> + repository exists, the following options apply to mercurial:
> + --git,
> + --git-min-signatures, --git-max-maintainers, --git-min-percent, and
> + --git-blame
> + Use --hg-since not --git-since to control date selection
> + File ".get_maintainer.conf", if it exists in the fstests source root
> + directory, can change whatever get_maintainer defaults are desired.
> + Entries in this file can be any command line argument.
> + This file is prepended to any additional command line arguments.
> + Multiple lines and # comments are allowed.
> + Most options have both positive and negative forms.
> + The negative forms for --<foo> are --no<foo> and --no-<foo>.
