Subject: Make ionice $command work
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddea327767d9280debfb5ae6671939d691040d2d;p=util-linux

Make ionice $command work

ionice $command would previously report:

  ionice: cannot parse number '$command'

This has been fixed so that it now tries to run the command under the
default I/O priority as per the man page.
