Subject: [PATCH] kobject: fix double kobject_put in kobject_unregister()
Date: Wed, 10 Nov 2004 22:19:23 +0000 [thread overview]
Message-ID: <20041110141923.A13668@unix-os.sc.intel.com> (raw)
Hi Greg,
This patch fixes the problem where in kobject resources were getting
freed when those kobject were still in use due to double kobject_put()
getting called in the kobject_unregister() code path.
With out this patch kobject_unregister() will have some serious side effects.
Please apply.
