Subject: lostup: report EACCES on loop-control
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=19cd36ebc2e227b2a93c70207b213da58f7be5e2;p=thirdparty%2Futil-linux.git

lostup: report EACCES on loop-control

Don't start scanning /dev/loop* after a failed access to
/dev/loop-control. It's a waste of time, and the user does not receive
a relevant error message.
