After using a loop device like:
mount -t iso9660 -o ro,loop=/dev/loop0 file /mnt
and then unmounting it later (umount /dev/loop0)
I can't mount /dev/loop0 again, I have to use loop1. Then loop2 and so on...
If I try to manually remove the loop module (rmmod loop) I get:
rmmod: loop: Device or resource busy
Which it shouldn't be 'cause its not mounted.
Anyone know what is wrong? Is this a bug or am I missing something. It
seems to me that I will have to reboot when i run out of loop devices,
since I can't seem to free them up.
I am running RedHat 2.2.16-3 kernel on a dual pII-450 with 512MB of RAM.
I compiled the kernel myself from the patched RedHat sources, so if you want
to know all what patches they put in just ask and I will tell you.
