btrfs-progs: btrfs_scan_kernel(): btrfs killed by SIGABRT https://bugzilla.redhat.com/show_bug.cgi?id=1711787
btrfs-progs-4.20.2-1.fc29 kernel:5.0.16-200.fc29.x86_64 If I understand the bug report correctly, one shell is watching for changing 'btrfs fi show' while another deletes a device, and then there's a crash. -- Chris Murphy
