[PATCH 0/3] Send: minor cleanups, add RO checks
First two patches are trivial cleanups that I''ve spotted while reading send.c,
can be applied independently.
The third patch contains the important bits, safety checks that the subvolumes
involved in send do not accidentally lose the RO status. I haven''t seen this
documented anywhere that this is mandatory, implied from how I assume send
works. Please let me know if this is

Set nodatacow per file?
Hello,
is it possible to set nodatacow on a per-file basis? I couldn''t find
anything.
If not, wouldn''t that be a great feature to get around the performance
issues with VM and database storage? Of course cloning should still
cause COW.
Thanks,
Ralf-Peter
