Hey.


I've just wondered whether:

means that send/receive v2 would now already be used when using
btrfsprogs v.19?

Especially,... is it considered stable?


Thanks,
Chris.

Progs use the highest version supported by the running kernel, the
version is detected from sys/fs/btrfs/features/send_stream_version . Not
using the latest version is up to the user in case the receiving side
does not support the version.

I'd say yes, the new features in v2 are not intrusive, eg. fileattr,
otime are only informative, the fallocate is not yet emitted on kernel
side and the encoded data have to be explicitly selected on the send
side. It's basically v1 with unless told otherwise.
