That's very kind of you to modify them by yourself.
I have already prepared branches for both property and btrfstune, but
you did it even before I send the v3 patchset.
Would you mind me to do all the modification you mentioned and send the
v3 patchset?
This should save some time for you.
Thanks,
Qu

All of the above merged (with some minor modifications), this covers
patches 1-7 from the first patchset. The btrfstune options are not
there, it needs some updates after I dropped the extra option to set the
chunk tree uuid.
The expected use:
* change the fsid to something that user specifies
* change the fsid but generate it randomly
* if the operation is interrupted, pick up the new fsid and continue
automatically, ie. the user does not have to remember uuid (this is
for convenience, the new fsid is stored in the superblock already and
can be obtained by show-super)
* the new chunk tree uuid has to be stored in some block, eg. the root
node of the tree_root; then picked from there when the uuid change
process is restarted
I'll get to that after doing the 4.0.1 release.
