The caller is expecte= d to call zfs_resume_fs() to release the locks, and it looks like that's handled properly. I think it'll be hard to track down what happened unless we can look at the lock state using a vmcore or so. I wonder if it'd be possible to re-trigger the deadlock, and then panic the system to collect a core dump? --=20 You are receiving this mail because: You are the assignee for the bug.=
