| H A D | audit_pipe.c | diff 293826 Wed Jan 13 12:06:20 MST 2016 kib Move the funsetown(9) call from audit_pipe_close() to cdevpriv destructor. As result, close method becomes trivial and removed. Final cdevsw close method might be called without file context (e.g. in vn_open_vnode() if the vnode is reclaimed meantime), which leaves ap_sigio registered for notification, despite cdevpriv destructor frees the memory later. Call destructor instead of doing a cleanup inline, for devfs_set_cdevpriv() failure in open. This adds missed funsetown(9) call and locks ap to satisfy audit_pipe_free() invariants.
