Nícolas F. R. A. Prado 6154fb9c21 kselftest: dt: Stop relying on dirname to improve performance ... When walking directory trees, instead of looking for specific files and running dirname to get the parent folder, traverse all folders and ignore the ones not containing the desired files. This avoids the need to call dirname inside the loop, which drastically decreases run time: Running locally on a mt8192-asurada-spherion, which reports 160 test cases, has gone from 5.5s to 2.9s, while running remotely with an nfsroot has gone from 13.5s to 5.5s. This change has a side-effect, which is that the root DT node now also shows in the output, even though it isn't expected to bind to a driver. However there shouldn't be a matching driver for the board compatible, so the end result will be just an extra skipped test: ok 1 / # SKIP Reported-by: Mark Brown <broonie@kernel.org> Closes: https://lore.kernel.org/all/310391e8-fdf2-4c2f-a680-7744eb685177@sirena.org.uk Fixes: 14571ab1ad ("kselftest: Add new test for detecting unprobed Devicetree devices") Tested-by: Mark Brown <broonie@kernel.org> Signed-off-by: Nícolas F.
