Today's issue was delayed due to your author taking a day off ahead of the US Memorial Weekend Holiday. Since I'll be in Ottawa, Canada over the weekend, the weekend update will likely be delayed until Monday evening.

In today's issue: putting struct inode on a diet, sparse interrupt allocation, union directories, zone reclaim defaults, and firewire interface naming conventions.
