[fuse-devel] Clone-file via FUSE

[Shachar S. <syn...@gm...>]

Hi all,
I want to implement file-cloning for FUSE based file system (use-case:
multiple vms which share single golden-image).

Unfortunately, btrfs' ioctl solution, used by coreutils to implement 'cp
--reflink...', will not work properly for FUSE
(
http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=45330176690b079ed47ac7c58f29a1b028f97b07
)

Did anyone implement such functionality for FUSE based file-system, via
ioctl or in any other way? What arguments did he pass over to the server?

Thanks in advance,
Shachar.
