Description
In the Linux kernel, the following vulnerability has been resolved:
md/raid1: fix memory leak in raid1_run()
raid1_run() calls setup_conf() which registers a thread via md_register_thread(). If raid1_set_limits() fails, the previously registered thread is not unregistered, resulting in a memory leak of the md_thread structure and the thread resource itself.
Add md_unregister_thread() to the error path to properly cleanup the thread, which aligns with the error handling logic of other paths in this function.
Compile tested only. Issue found using a prototype static analysis tool and code review.
