Subject: [PATCH 1/2] tests: cleanup losetup usage
|
|
|
|
The unsafe_losetup_ function was failing because losetup didn't
|
|
recognize that the 'private' /dev/loopX devices were the same as
|
|
/dev/loopX, it would fail even if one was in use. Switch to using
|
|
losetup --show which is a cleaner solution.
|
|
Also use sparse file for loop_setup to save space.
