Example: https://evilpiepirate.org/~testdashboard/c/82973f03c0683f7ecebe14dfaa2c3c9989dd29fc/xfstests.generic.388/log.br I haven't personally seen it on xfs - Darrick knew something about it but he's on vacation. If I track down a reproducer on xfs I'll let you know. If you're wanting to dig into it on bcachefs, ktest is pretty easy to get going: https://evilpiepirate.org/git/ktest.git $ ~/ktest/root_image create # from your kernel tree: $ ~/ktest/build-test-kernel run -ILP ~/ktest/tests/bcachefs/xfstests.ktest/generic/388 I have some debug code I can give you from when I was tracing it through the mount path, I still have to find or recreate the part that tracked it down to io_uring...
