How? From What I see znode is freed via zfs_znode_free() called from znode_pageout_func(). I don't think I can just call zfs_znode_free(), as I'm quite sure there are some dependent resources I need to release. Which function should I used for this? -- Pawel Jakub Dawidek http://www.wheel.pl pjd at FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
