It's a race: [ 1289.578972] LTP: starting mtest06 ( mmap1) ... [ 1455.794564] kernel BUG at mm/filemap.c:171! Here's a verbose description: https://lore.kernel.org/lkml/50b8914e20d1d62bb2dee42d342836c2c16ebee7.1563438048.git.jstancek@redhat.com/ Final (less verbose) patch: e1b98fa31664 ("locking/rwsem: Add missing ACQUIRE to read_slowpath exit when queue is empty") Code review found also this issue, which is theoretical and very unlikely, but it's a small patch: 99143f82a255 ("lcoking/rwsem: Add missing ACQUIRE to read_slowpath sleep loop") Regards, Jan
