g_dev_orphan(): Return early if the device is already gone
The following panic was the result of running "cdcontrol eject" after
using the physical ejection key on the device before the tray was
actually ejected. So we have hardware racing software.
The device was loaded with a DVD.
Resulted in a NULL pointer dereference
g_dev_orphan() at g_dev_orphan+0x2e/frame 0xfffffe01eba0a9f0
g_resize_provider_event() at g_resize_provider_event+0x71/frame
0xfffffe01eba0aa20
g_run_events() at g_run_events+0x20e/frame 0xfffffe01eba0aa70
fork_exit() at fork_exit+0x85/frame 0xfffffe01eba0aab0
fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe01eba0aab0
Avoid this possibility and return early of dev is NULL already.

Hi all,
I am extremely sorry for this query.
The issue "mnt_vnode_next_active: use conventional lock order when trylock
fails." exists in 11.4 too but I noticed that it is not being ported to
11.4, but ported only till 12.0 Reference commit:
https://github.com/freebsd/freebsd-src/commit/391aba32e6d308a8fd0ac12ee49495119c7a307c
(May
15, 2017)
May I request you to please share the reason for porting it only till 12.0
but not in 11.4 though the issue exists in 11.4.
I had noticed that other fixes like the below are ported to 11.4 though
(which are ported after May 15, 2017)

I can't tell, but in any case, FreeBSD 11 has been out of support for four years
now. Please consider updating to FreeBSD 14.

g_dev_orphan(): Return early if the device is already gone
The following panic was the result of running "cdcontrol eject" after
using the physical ejection key on the device before the tray was
actually ejected. So we have hardware racing software.
The device was loaded with a DVD.
Resulted in a NULL pointer dereference
g_dev_orphan() at g_dev_orphan+0x2e/frame 0xfffffe01eba0a9f0
g_resize_provider_event() at g_resize_provider_event+0x71/frame
0xfffffe01eba0aa20
g_run_events() at g_run_events+0x20e/frame 0xfffffe01eba0aa70
fork_exit() at fork_exit+0x85/frame 0xfffffe01eba0aab0
fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe01eba0aab0
Avoid this possibility and return early of dev is NULL already.
