From: Darrick J. Wong Date: Thu, 21 Jul 2016 23:47:32 +0000 (-0700) Subject: reflink: test cross-mountpoint reflink and dedupe X-Git-Tag: v2022.05.01~2396 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=72cdba7141675c8d6a807ff92f217712aed6e044;p=users%2Fhch%2Fxfstests-dev.git 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.
