Subject: Re: [PATCH v2 6/9] xen/sys-hypervisor: Add release callback to hyp_sysfs_kobj_type
Date: Tue, 27 Oct 2026 22:42:12 +0000 [thread overview]
Message-ID: <sashiko-outbox-187170@kernel.org> (raw)
In-Reply-To: <20261027223847.652884-7-irogers@google.com>
> hypervisor_init() in drivers/base/hypervisor.c creates hypervisor_kobj
> with kobject_create_and_add() (which allocates a dynamic kobject using
> dynamic_kobj_ktype), and hypervisor_subsys_init() in
> drivers/xen/sys-hypervisor.c then overwrites hypervisor_kobj->ktype with
> &hyp_sysfs_kobj_type, which had no .release callback.
>
> Add hyp_sysfs_release() calling kfree(kobj) to preserve the dynamic
> kobject release behavior.
>
> Fixes: cff7e81b3dd7 ("xen: add /sys/hypervisor support")
> Signed-off-by: Ian Rogers <irogers@google.com>
