Repost [uml-devel] [PATCH] fix for: Host panic when UML reads host /dev/shm

[BlaisorBlade]

Ok here are the two patches one each for 2.4.23
and 2.6.0-test11
Linus has accepted the test11 patch into bk so
the next 2.6 kernel should have the fix
I have also been testing a 2.4.23 patch
They no longer oopes with any of my test programs
Since you were having problems here they are

Enjoy, James McMechan
