From: Junio C Hamano Date: Tue, 21 Dec 2010 17:24:18 +0000 (-0800) Subject: set_try_to_free_routine(NULL) means "do nothing special" X-Git-Tag: v1.7.4-rc0~21 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=00b0d7f77b65ed2d059f893bbd2011ba5bb4252d;p=git.git set_try_to_free_routine(NULL) means "do nothing special" This way, the next caller that wants to disable our memory reclamation machinery does not have to define its own do_nothing() stub.
