Subject: Re: Commenting out out_of_memory() function in __alloc_pages()
Date: Fri, 7 Jul 2006 04:54:41 -0500	[thread overview]

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

main()
{
	char* buff;
	int count;
	
	count=0;
	while(1)
	{
		printf("\nOOM Test: Counter = %d", count);
		buff = (char*) malloc(1024);
	//	memset(buff,'\0',1024);
		count++;
			
		if (buff==NULL)
		{
			printf("\nOOM Test: Memory allocation error");
		}
	}
}
