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 <[email protected]> (maintainer:DRM DRIVERS) Daniel Vetter <[email protected]> (maintainer:DRM DRIVERS,commit_signer:3/42=7%) Qiang Yu <[email protected]> (commit_signer:36/42=86%,authored:24/42=57%) Vasily Khoruzhick <[email protected]> (commit_signer:26/42=62%) Krzysztof Kozlowski <[email protected]> (commit_signer:5/42=12%,authored:5/42=12%) Emil Velikov <[email protected]> (commit_signer:4/42=10%) [email protected] (open list:DRM DRIVERS) [email protected] (open list) # (without double slash) $ ./scripts/get_maintainer.pl -f drivers/gpu/drm/lima Qiang Yu <[email protected]> (maintainer:DRM DRIVERS FOR LIMA) David Airlie <[email protected]> (maintainer:DRM DRIVERS) Daniel Vetter <[email protected]> (maintainer:DRM DRIVERS) [email protected] (open list:DRM DRIVERS FOR LIMA) [email protected] (moderated list:DRM DRIVERS FOR LIMA) [email protected] (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 "/.".
