try to simplify the locking code around busy maps. vm_maps have a "feature" where they can mark that they're being operated on by a specific proc, and then release the rwlock protecting their state. to relock, you have to be the same proc that marked it busy. this diff tries to simplify it a bit. it basically has threads check the busy field up front and rechecks the busy field inside the rwlock. if you can sleep, it will sleep up front for the busy field to become clear, rather than sleep on either the busy field or the rwlock. some code paths clear the busy field without holding the rwlock, so it doesn't make sense to me to be waiting for the busy field but sleeping somewhere else. ok claudio@ mpi@ |
