Hello, In the past few days, I have managed to remove Giant from sysctl. The patch is at http://people.freebsd.org/~ssouhlal/testing/sysctl-locking.diff This is the first time I ever do something like this, so I wouldn't be surprised if I am doing something wrong. Any suggestions/comments? green@ also pointed out that I might need to use memory barriers, or some other synchronization primitive, when setting oid_owner to NULL in sysctl_oid_disown, but I am unsure on how to do that.. Thanks in advance for your help. -- Suleiman Souhlal | ssouhlal@vt.edu The FreeBSD Project | ssouhlal@FreeBSD.org
