That is an stress test, resulting in a failure:
In command console, three big files are mounted with uloop, mount gets locked
showing the following message:
ulobdev: ulobdev.c:53: store: Assertion `start + size <= uloop->cache_size'
failed
Command sequence:
mkdir /tmp/f
ulobdev -b /tmp/b -c /tmp/c /dev/loop5
/home/live/testing-personal/pcqjordi.squashfs
mount -t squashfs /dev/loop5 /tmp/f
mount: block device /dev/loop5 is write-protected, mounting read-only
mkdir /tmp/g
ulobdev -b /tmp/d -c /tmp/e /dev/loop6
/home/live/testing-personal/pcquim.squashfs
mount -t squashfs /dev/loop6 /tmp/g
mount: block device /dev/loop6 is write-protected, mounting read-only
ulobdev: ulobdev.c:53: store: Assertion `start + size <=
uloop->cache_size'
failed.
