Hi.
In our regression, there is a test case in which we register the last
VMA of a process that has a read permission.
Only in kernel 2.6.20-rc5 i get a failure.
Here is the last line that i got from executing "cat /proc/1873/maps":
In kernel 2.6.16.21-0.8-smp:

[vdso]
It seems that in kernel 2.6.20-rc5 the last VMA which has a read
permission is the [vdso] section but when i try
to register it i get a failure.
Is it wrong to register this section?
thanks
Dotan
