From 1fa6ead492c81bffdbe336373e5b162d3b5ac6d3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 22 Mar 2008 09:48:41 -0700 Subject: [PATCH] Make unpack-tree update removed files before any updated files This is immaterial on sane filesystems, but if you have a broken (aka case-insensitive) filesystem, and the objective is to remove the file 'abc' and replace it with the file 'Abc', then we must make sure to do the removal first. Otherwise, you'd first update the file 'Abc' - which would just overwrite the file 'abc' due to the broken case-insensitive filesystem - and then remove file 'abc' - which would now brokenly remove the just updated file 'Abc' on that broken filesystem. By doing removals first, this won't happen.
