Enable the 'skip_cache_tree_update' option in the variants that call 'prime_cache_tree()' after 'unpack_trees()' (specifically, 'git reset --mixed' and 'git reset --hard'). This avoids redundantly rebuilding the cache tree in both 'cache_tree_update()' at the end of 'unpack_trees()' and in 'prime_cache_tree()', resulting in a small (but consistent) performance improvement. From the newly-added 'p7102-reset.sh' test: Test before after -------------------------------------------------------------------- 7102.1: reset --hard (...) 2.11(0.40+1.54) 1.97(0.38+1.47) -6.6% Signed-off-by: Victoria Dye <vdye@github.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>
