This is caused by two lock operations on the page. == Fix == Upstream ZFS fix to ensure the page is not double-locked during async I/O of one or more pages. == Testing == Create a zfs pool + zfs file system, run the reproducer program in comment #28 on the zfs filesystem. Without the fix this can lock up, with the fix this runs to completion. == Regression Potential == Minimal, the locking fix addresses a fundamental bug in the locking and this should not affect ZFS read/write I/O with this fix. ---------------------- Summary: On a Bionic system running 4.15.0-10-generic, after attempting to build libaio in a Bionic daily container I cannot stop or delete the container. dmesg shows a variety of hung tasks Steps to Reproduce: Use the following script and watch for the the hang.
