Before read locking z_teardown_inactive_lock, we need to check if we have already had write lock on it. Otherwise, we would deadlock on ourself when doing rollback: zfs_ioc_rollback ->zfs_suspend_fs (z_teardown_inactive_lock, RW_WRITER) ->zfs_resume_fs->zfs_rezget->zfs_iput_async->iput-> ... ->zfs_inactive (z_teardown_inactive_lock, RW_READER) Signed-off-by: Chunwei Chen <tuxoko@gmail.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2869 |
