Subject: [PATCH] vt: Decrement ref count of the VT backend on deallocation
Date: Sun, 02 Jul 2006 11:41:06 +0800 [thread overview]
Message-ID: <44A74052.1070506@gmail.com> (raw)
When a VT is newly allocated, the module reference count of the backend will
be incremented. This should be balanced by a module_put() when this VT is
deallocated.
