As reported in [1] the "UNUSED(var)" macro introduced in2174b8c75d
(Merge branch 'jk/unused-annotation' into next, 2022-08-24) breaks coccinelle's parsing of our sources in files where it occurs. Let's instead partially go with the approach suggested in [2] of making this not take an argument. As noted in [1] "coccinelle" will ignore such tokens in argument lists that it doesn't know about, and it's less of a surprise to syntax highlighters. This undoes the "help us notice when a parameter marked as unused is actually use" part of9b24034754
(git-compat-util: add UNUSED macro, 2022-08-19), a subsequent commit will further tweak the macro to implement a replacement for that functionality. 1. https://lore.kernel.org/git/220825.86ilmg4mil.gmgdl@evledraar.gmail.com/ 2. https://lore.kernel.org/git/220819.868rnk54ju.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
