Abstract
When copy commands are queued in a submission queue, there can potentially be many queued input-output (I/O) commands directed to the same logical range as the queued commands. This can result in data being invalidated immediately after it is written in memory, leading to write amplification and inefficient backend processing. To address this problem, the embodiments presented herein can be used to lock the range of logical block addresses of the queued commands, so that I/O commands are prevented from accessing the range of logical block addresses until the queued copy commands are completed.
