[Qemu-devel] [PATCH v2 11/15] blockjob: Add 'id' parameter to 'block-job-cancel' |
Date: |
Wed, 22 Jun 2016 15:25:08 +0300 |
This patch allows the 'block-job-cancel' command to identify the
job by either its ID or its device name. The latter becomes now
optional since the ID alone is enough to identify the job.
The HMP 'block_job_cancel' command remains unchanged.
