That does not look right. Sure wish that the percpu allocator would be working from atomic contexts for other cases. > http://lkml.org/lkml/2009/10/27/215 There is still heavy percpu use because of the patch for machines with large numbers of processors. Another solution would be better that does not require a N^2 sized array. -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
