Module Name:	src
Committed By:	riastradh
Date:		Fri Apr 19 00:45:41 UTC 2024

Modified Files:
	src/sys/kern: vfs_mount.c

Log Message:
dounmount: Avoid &((struct vnode_impl *)NULL)->vi_vnode.

Member access of a null pointer is undefined, even if the result
should also be null because vi_vnode is at the start of vnode_impl.
