inotify-0.18-rml-4: Oops

[Juerg Billeter]

Hi

I reproducibly get the following Oops as soon as I start using inotify
with gamin and/or beagle. This happens with linux 2.6.10-as1 + inotify
0.18-rml-4 on multiple x86 machines.

Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:
c01d6d31
*pde = 00000000
