Hi Darrick,

Thanks for your explanation.

rmapbt, reflink and dedupe features will be enabled by default together?

Thanks

Hi Darrick,

Sorry to bother you.

Currently, all reflink tests for XFS in xfstests are skipped even if we
use the lastest kernel and xfsprogs.
It seems that mkfs.xfs doesn't enable reflink by default, do you want to
enable it by default in later
xfsprogs version?
It will be enabled by default when we've had a long enough period to
test it and make sure it's stable for general use.  That may happen some
time in early 2019.

Shoud we enable it forcely by "mkfs.xfs -m reflink" in
xfstests if mkfs.xfs supports it?
For now, yes.

--D

Thanks,
Xiao Yang
