## Description

In the Linux kernel, the following vulnerability has been resolved:  rxrpc: fix io_thread race in rxrpc_wake_up_io_thread()  rxrpc_wake_up_io_thread() checks local->io_thread before waking it, but then reloads the pointer for wake_up_process().  local->io_thread is cleared with WRITE_ONCE() when the I/O thread exits, so the second load can see NULL even if the first load did not.  Take a READ_ONCE() snapshot and use it for both the NULL check and the wake_up_process() call, as rxrpc_encap_rcv() already does.
