Yeah :(..sorry abt that, I'd actually tested an earlier patch of
yours (one u sent to Dipankar) and I'd got an oops in
__alloc_percpu (Same application but I'd actually called
init_commmited_space earlier). So when I got a oops again
with the newer patch, I just mailed it.
But still, even after actually calling init_committed_space
with the newer patch (The first one which you mailed to Andrew in this
thread) I get an oops at __alloc_percpu.
Here's the oops report...looks like the
struct pcpu_block *pcpu has NULL...
Thanks,
Kiran
