From: Stephen Warren <swarren@nvidia.com>

This reverts most of eb90d08 "get_maintainer: allow keywords to match
filenames"; all except the parts that are required to implement the new
N: entry type.

The rationale is that it's better to have K: match just patch or file
content as it previously did, and N: match just filenames, rather than
have K: math all three cases. This gives more explicit control, and
removes the temptation to use K: for filenames, and then have those
keywords accidentally match unexpected patch or file content.

Just combine patches 1 and 3 into a single patch.

That would break bisectability; using MAINTAINERS after applying a
squashed 1+3 but without patch 2 applied would not operate as desired.

<smile>

Which is why I showed the whole thing in a single patch.
No worries if it's simply to increase the patch count...

cheers, Joe

I'm not sure what showed refers to?

I guess if I squashed /everything/ into a single commit (i.e. the change
to the Tegra section in MAINTAINERS too) then there wouldn't be any
bisect issues. I really don't care about patch count. The reason for >1
patch is that there's often push-back if doing logically separate things
(adding N: feature, modifying a MAINTAINERS entry to use it, removing
part of K: feature) in a single patch...

The changes I posted with the suggestion

Not from me anyway.

I think it's a single logical change and
it's trivial too.

No worries whatever happens.
