More info:
I did the loop mount as usual:
sudo mount -o loop my-big.iso /mnt/tmp1
I noticed that each time the loop device number increased. When I do ps, I
found that there are still many loop process in execution:
$ ps -eaf | grep loop
root 5566 1 0 Jan05 ? 00:01:44 [loop0]
root 5597 1 0 Jan05 ? 00:00:00 [loop1]
root 5603 1 0 Jan05 ? 00:00:00 [loop2]
root 10995 1 0 00:28 ? 00:01:41 [loop3]
root 26656 1 0 11:42 ? 00:01:40 [loop4]
root 6234 1 0 17:45 ? 00:00:00 [loop5]
please comment
thanks
