Subject: [PATCH 168/173] losetup: keep -f and <devname> mutually exclusive
|
||
|
|
|
||
|
|
losetup tries to blindly use specified device as well as search for
|
||
|
|
the first free device, the result is:
|
||
|
|
|
||
|
|
# losetup /dev/loop1 -f /tmp/tfile_loop1
|
||
|
|
losetup: /dev/loop1: failed to set up loop device: Invalid argument
|
||
|
|
|
||
|
|
fixed version:
|
||
|
|
|
||
|
|
# losetup /dev/loop10 -f img
|
||
|
|
losetup: unexpected arguments
|
||
