Hi Andrew,
This patch does not fix the NULL dereferencing issue yet. Wei is going to
1. send a patch to fix the bug on top of mm-stable,
2. resend this patchset on top of the fix in 1.
This might be easier for back porting the fix. Maybe you can drop this series
for now.
Wei, do you agree?
Best Regards,
Yan, Zi
