Andriy Gapon 74f75cb1bd zfs_mount(MS_REMOUNT): protect zfs_(un)register_callbacks calls ... We now take z_teardown_lock as a writer to ensure that there is no I/O while the filesystem state is in a flux. Also, zfs_suspend_fs() -> zfsvfs_teardown() call zfs_unregister_callbacks() and zfs_resume_fs() -> zfsvfs_setup() call zfs_unregister_callbacks(). Previously there was no synchronization between those calls and the calls in the re-mounting case. That could lead to concurrent execution and a crash.
