Research direction

Start by locating the vmstat implementation and the output path for the -D option, then find the label for I/O requests currently in progress. Update the label to match procps-ng's "inprogress IO" wording and verify that vmstat -D exits successfully with the expected output.

Written by the indexing model from the issue text.

Description

uutils vmstat -D labels the number of I/O requests currently in progress as in progress IO. procps-ng 4.0.7 uses inprogress IO:

procps-ng:             0 inprogress IO
uutils:                0 in progress IO

Only the label differs in this comparison. Both commands exit 0 with empty stderr.
