From e06c43c7959042e5612984b8193700f32f12b2be Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 30 Mar 2008 09:25:52 -0700 Subject: write_index(): optimize ce_smudge_racily_clean_entry() calls with CE_UPTODATE When writing the index out, we need to check the work tree again to see if an entry whose timestamp indicates that it could be "racily clean", in order to smudge it if it is stat-clean but with modified contents. However, we can skip this step for entries marked with CE_UPTODATE, which are known to be the really clean (i.e. the one we already have checked when we prepared the index). This will reduce lstat(2) calls necessary in git-status.
