Subject: [PATCH] 'zfs receive' fails with "dataset is busy"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Receiving an incremental stream after an interrupted "zfs receive -s"
fails with the message "dataset is busy": this is because we still have
the hidden clone ../%recv from the resumable receive.
Improve the error message suggesting the existence of a partially
complete resumable stream from "zfs receive -s" which can be either
aborted ("zfs receive -A") or resumed ("zfs send -t").
