Mail for linux-kernel@vger.kernel.org

As you probably know, cause this version of the kernel has been running for so long the loopback block driver fails.

In the loop.c file there are 3 calls to 2 functions that are not implemented all over the kernel. These funcions are:

	deactivate_page  (Used in lines 210 and 221)
	BUG              (Used in line 453 inside of a simple conditional sentence)

To solve this failure i just commented these lines and seems that works as a module and as part of the kernel too.

This is the output of the ver_linux script:
