RE: Commenting out out_of_memory() function in __alloc_pages()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The funniest part is that with memset commented out_of_memory observed,
contrary to my expectation.

I don't know why. It shouldn't have. I am running the application on an ARM
target.

Regards,
Abu.

I am not sure about x86, but on ia64, you would be very hard pressed
for this application to actually run you out of memory.  With the
memset commented out, you would be allocating vmas, etc, but you
would not be actually putting pages behind those virtual addresses.

Thanks,
Robin
