From 58ecbd5edeb2357c313db75bc49d45981a2061b7 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sat, 6 Nov 2010 06:44:11 -0500 Subject: [PATCH] wrapper: move xmmap() to sha1_file.c wrapper.o depends on sha1_file.o for a number of reasons. One is release_pack_memory(). xmmap function calls mmap, discarding unused pack windows when necessary to relieve memory pressure. Simple git programs using wrapper.o as a friendly libc do not need this functionality. So move xmmap to sha1_file.o, where release_pack_memory() is.
