Dear syzbot, thank you. So far I think this is another problem revealed by aaec5a95d59615523db03dd5 ("pipe_read: don't wake up the writer if the pipe is still full"). I am going to forget about this report for now and return to it later, when all the pending pipe-related changes in vfs.git are merged. Oleg.
