Currently most of the UFS io bypasses devfs vnode layer, but this is not an architectural property. We cannot guarantee that= UFS operations would not require a VOP call into devfs which is not grounded by= a panic (see vfs_default.c). --=20 You are receiving this mail because: You are the assignee for the bug.=
