chore: replace {0, 0} with {DEV,KOBJ}METHOD_END

2026-02-25T05:59:34+00:00

Both of the aforementioned macros have been present in FreeBSD
for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for
`DEVMETHOD_END`.

Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`
and `KOBJMETHOD_END` as appropriate. This helps ensure that
future adaptations to drivers following patterns documented
in driver(9) can be made more easily/without issue.

ciss: Don't panic on null CR ciss_dequeue_notify

2024-10-14T05:37:46+00:00

Apparently, sometimes on hot plug/unplug, a null cr comes back from
ciss_dequeue_notify. This is clearly a bug, and by ignoring it we're
papering over that bug. We only ever wake the thread after enqueing a
notification or setting a bit about killing the thread, so once we check
the bit isn't the cause, cr can't be NULL unless something else has
dequeued it.

Ideally, this would be fixed, rather than papered over, but this makes a
very old card somewhat more useable for external enclosures. I suspect
it's a race when we set CISS_THREAD_SHUT and another flag (the latter
w/o ciss_mtx held), but I don't see it and w/o hardware to reproduce
it would be hard to know for sure.
