get_maintainer behaves differently if there is a double sequential forward slash in a filename because the total number of slashes in a filename is used to match MAINTAINERS file patterns. For example: (with double slash) $ ./scripts/get_maintainer.pl -f drivers/gpu/drm//lima David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS) Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS,commit_signer:3/42=7%) Qiang Yu <yuq825@gmail.com> (commit_signer:36/42=86%,authored:24/42=57%) Vasily Khoruzhick <anarsoul@gmail.com> (commit_signer:26/42=62%) Krzysztof Kozlowski <krzk@kernel.org> (commit_signer:5/42=12%,authored:5/42=12%) Emil Velikov <emil.velikov@collabora.com> (commit_signer:4/42=10%) dri-devel@lists.freedesktop.org (open list:DRM DRIVERS) linux-kernel@vger.kernel.org (open list) (without double slash) $ ./scripts/get_maintainer.pl -f drivers/gpu/drm/lima Qiang Yu <yuq825@gmail.com> (maintainer:DRM DRIVERS FOR LIMA) David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS) Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS) dri-devel@lists.freedesktop.org (open list:DRM DRIVERS FOR LIMA) lima@lists.freedesktop.org (moderated list:DRM DRIVERS FOR LIMA) linux-kernel@vger.kernel.org (open list) So reduce consecutive double slashes to a single slash by using File::Spec->canonpath(). from: https://perldoc.perl.org/File/Spec/Unix.html canonpath() No physical check on the filesystem, but a logical cleanup of a path. On UNIX eliminates successive slashes and successive "/.".

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
