The patch against loop.c is neither a fix, nor does it create loop devices on demand:

It does. In kernel memory.

Quoted 11 lines
Quoted 11 lines

Facts are instead, at least on my machine:

The number of available loop devices is reduced from 8 (conventional standard of preceding 2.6 kernels) to 1.

The consequence is: If you have to mount more than one single iso-image with
the loop parameter you are receiving the following message during system boot:

"mount: could not find any free loop device"

I suggest to read mknod(1) manpage.

While it worked in 2.6.21, that was pretty much the only point-release kernel where it did. In other words, I'm honestly not sure I'd classify this as a regression given it worked exactly once :-/. So, I'd suggest pulling this from the list for now unless Len decides otherwise.

That should be fixed now. It was actually a regression in 2.6.19 :)

Cheers,
