[RFC PATCH 0/2] scripts: warn about invalid MAINTAINER patterns

[Tom Saeger <tom.saeger@oracle.com>]

This series attempts to fix all stale MAINTAINER file "F" and "X" patterns.

First patch adds an option "checks" to get_maintainer.pl which outputs
warnings for any "F" or "X" pattern found in MAINTAINER file which does
not register any file/directory matches known by git in current worktree.

Originally, I wrote a standalone script "check_maintainer", but as this
duplicated some of the functions found in get_maintainer.pl it seemed to
make more sense to change get_maintainer.pl directly.

The "-x|--checks" option is intended to be used as follows:

./scripts/get_maintainer.pl -x ./ | tee out.txt
./MAINTAINERS:1743      warning: no matches     drivers/.*/pm8...-.*    F:      drivers/*/pm8???-*
./MAINTAINERS:8721      warning: no matches     drivers/net/ethernet/mellanox/mlx5/core/en_ipsec/.*     F:      drivers/net/ethernet/mellanox/mlx5/core/en_ipsec/*
./MAINTAINERS:8722      warning: no matches     drivers/net/ethernet/mellanox/mlx5/core/ipsec.* F:      drivers/net/ethernet/mellanox/mlx5/core/ipsec*
./MAINTAINERS:9431      warning: no matches     net/core/flow\.c        F:      net/core/flow.c


The output format lends itself to the following in vim (note tab
character):
set errorformat=%f:%l\	%m
cfile out.txt
copen


Second patch fixes all MAINTAINER warnings but four (those listed above), which were not
obvious to me how to fix.  Most fixes were obvious, requiring only "ls
./**/*pat*" or "git log --follow -- xyz.c" or "git blame MAINTAINERS" to
figure out what needed to be changed.

Patches are independent, however I did employ the first in figuring out the
second.

Looking for input on how best to get these merged.  Some of these have
been broken for a long time - so stable kernels might benefit from
backporting.

Future enhancements could sanity check all the other entry types found in
MAINTAINER file.
