If a cluster filesystem is using ACL caching (added by Viro a little while back), they use forget_all_cached_acls() at lock drop time to make sure they don't have stale ACL info. We're not using cached_acls yet, but if someone adds it, please remember this call ;-) Joel -- Life's Little Instruction Book #444 "Never underestimate the power of a kind word or deed." http://www.jlbec.org/ jlbec at evilplan.org
