Thanks for the info.
I also read the phoronix news yesterday.
So for RHEL6 that's meaningless.
But I'm not sure whether it's still meaningless for OpenSUSE, maybe
David has some plan on it?
Thanks,
Qu

Hi David, Mark,
In the recent test for new btrfs-convert backward compatibility, I
found that cmds-fi-du.c uses FIEMAP_EXTENT_SHARED bits, which is not
present in kernel of old distributions like RHEL6 (Sorry, didn't test
on openSUSE equivalent).
There is really no need to invest in compatibility with such old
distros IMHO. As Phoronix breathlessly points out today, the tech preview
of btrfs in RHEL6 has ended, and it is now deprecated in RHEL6.
RHEL6-era btrfs was an interesting experiment, but it is one that will
not continue.
Thanks,
-Eric
