Are you effectively saying this patch will turn into a no-op once its been munged through the various patch management tools? That's disappointing because it's a pain to have to invoke everything though bash explicitly. Many other scripts manage to have the correct execute permission set (see everything in ./scripts for example). Personally I'd rather keep this patch and try rather than proactively do a work around. > > [1] https://lore.kernel.org/all/20230103180754.129637-5-sj@xxxxxxxxxx/ > [2] https://lore.kernel.org/mm-commits/YRJisBs9AunccCD4@xxxxxxxxx/ > [3] https://lore.kernel.org/all/20210810164534.25902-1-sj38.park@xxxxxxxxx/ > [4] https://lore.kernel.org/stable/2023042743-cheesy-parasitic-206d@gregkh/ > > > Thanks, > SJ > >> >> >> Reviewed-by: David Hildenbrand <david@xxxxxxxxxx> >> >> -- >> Cheers, >> >> David / dhildenb >> >> >>
