That means we need both the anon_vma locks and the i_mmap_lock to become semaphores. I think semaphores are better than mutexes. Rik and Lee saw some performance improvements because list can be traversed in parallel when the anon_vma lock is switched to be a rw lock. Sounds like we get to a conceptually clean version here? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
