I used the attached diff, with hackish snooping
on allocated/freed memory for vnodes. When the vp pointer have been
logged as active1/active2, it is (much) later shown with
dead_vnodeops in DUMP_VP().
Is there a lot of such /dev/ttyp* vnodes ? This indeed might be
suspicious. See below for description of how to check that the
vnodes are leaked or not.
In VP_DUMP, there have been 90% nodes of this type:
40285 active 0xffffff00164855a0 tag devfs type 8 flags 00000080 use count 1
hold count 1
19410 active 0xffffff0024522d20 tag devfs type 8 flags 00000080 use count 1
hold count 1
258526 active 0xffffff000a93b960 tag devfs type 8 flags 00000080 use count 1
hold count 1
257411 active 0xffffff00245d8b40 tag devfs type 8 flags 00000080 use count 1
hold count 1
247494 active 0xffffff0016c7d780 tag devfs type 8 flags 00000080 use count 1
hold count 1
None of other line have VI_DOOMED set.
The tag in my output is devfs, due to commented out vp->v_tag = "none";
I do not know, what the previous name (like ptyp*) have been.
