From 630a2890fff1e3f8f53e9a708d5e6fb2b5158566 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 21 Oct 2013 17:52:08 +0000 Subject: [PATCH] xfstests: add regression test for kernel bz 60673 V2 There was a problem with send trying to overwrite a file that wasn't actually the same. This is a test to check this particular case where receive fails when it should succeed properly. I tested this to verify it fails without my fix and passes with my fix.
