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
