pipe: Check for ring full inside of the spinlock in pipe_write() Make pipe_write() check to see if the ring has become full between it taking the pipe mutex, checking the ring status and then taking the spinlock. This can happen if a notification is written into the pipe as that happens without the pipe mutex. Signed-off-by: David Howells <dhowells@redhat.com>
