From 72cdba7141675c8d6a807ff92f217712aed6e044 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 21 Jul 2016 16:47:32 -0700 Subject: [PATCH] reflink: test cross-mountpoint reflink and dedupe Test sharing blocks via reflink and dedupe between two different mountpoints of the same filesystem. This shouldn't work, since we don't allow cross-mountpoint functions. Signed-off-by: Darrick J.
