Hi all,

I Have following question with regard for 2.6.30 kernel

 If we do double kfree()

a) Then what will happen?
b) Can kernel detect double kfree() ?


I gone through google to find some way to find it, there it mention
CONFIG_DEBUG_SLAB can help, but i am not sure how usefull is it.

I have two targets will it support on both ?


Thanks
