From d6c88c4fdc1ce189e4abad56f9e3b16d2f831867 Mon Sep 17 00:00:00 2001 From: Thomas Gummerer Date: Mon, 8 Jul 2019 17:33:03 +0100 Subject: [PATCH] apply: only pass required data to skip_tree_prefix Currently the 'skip_tree_prefix()' function takes 'struct apply_state' as parameter, even though it only needs the p_value from that struct. This function is in the callchain of 'parse_git_header()', which we want to make more generally useful in a subsequent commit. To make that happen we only want to pass in the required data to 'parse_git_header()', and not the whole 'struct apply_state', and thus we want functions in the callchain of 'parse_git_header()' to only take arguments they really need.
