From 239d2cbdb0a4c32df9f21de8385e2c466b934178 Mon Sep 17 00:00:00 2001 From: Vikas Gorur Date: Thu, 17 Sep 2009 05:56:24 +0000 Subject: libglusterfs: Add checksum functions. gf_rsync_weak_checksum: Calculates a simple 32-bit checksum. gf_rsync_strong_checksum: Calculates the MD5 checksum. The strong checksum function makes use of Christophe Devine's MD5 implementation (adapted from the rsync source code, version 3.0.6. ). Signed-off-by: Anand V.
