[PATCH/RFC 2.6.21 1/5] ehca: declaration of queue structures
From: Hoang-Nam Nguyen <hidden>
Date: 2007-01-11 19:11:37
Hello Roland and Christoph H.! This is a patch for ehca structs. It enhances completion queue and queue pair with use counters for associated mmap-ed resources, ie. hardware register block and queue pages. Furthermore it removes redundant prototypes.
