The recent fix to put_ldev() (correct ordering of access to local_cnt and state.disk; memory barrier in __drbd_set_state) guarantees that the cleanup happens exactly once. However it does not yet guarantee that the cleanup happens from worker context, the last put_ldev() may still happen from atomic context, which must not happen: blkdev_put() may sleep. Fix this by scheduling the cleanup to the worker instead, using a couple more bits in device->flags and a new helper, drbd_device_post_work(). Generalized the "resync progress" work to cover these new work bits. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com> |
