If so, please tell me, what is the first confirmed kernel version, which
supports this. Or at least, is it available on Kernel 3.5.
I know, that it is possible to assign nodatacow attribute to files with
"chattr +C ", if the file has zero length.
Thank you

Walking backref tree and btrfs quota rely on ulist very much.
This patch tries to use rb_tree to speed up search time.
The original code always checks whether an element
exists before adding a new element, however it costs O(n).
I try to add a rb_tree in the ulist,this is onl

The parent UUID, all generation values and all timestamps that
are available in the root_item are added.

If one of the copy of the superblock is zero it does not
confirm to us that btrfs isn't there on that disk. When
we are having more than one copy of superblock we should
rather let the for loop to continue to check other copies.
the following test case and results would justify the
fix
mkfs.btrfs
