Commit message

usr/lib/byobu/disk_io: LP: #1626218
remove disk_io status notification when it drops below the $DISK_IO_THRESHOLD

Description of the change

When the disk_io status notification is enabled and the machine's IO first exceeds $DISK_IO_THRESHOLD (defaults to 50kB/s), the status notification appears. If both the read and write IO drop below the threshold, the status notification is not removed, and instead its last value is displayed until the threshold is later exceeded and the old notification is overwritten.

This patch removes the notification once the IO drops below the threshold, closing LP #1626218.
