We may not free tl_hash when IO is suspended, since we can not wait until ap_bio_cnt reaches zero. We can do this after susp reched 0, since then tl_clear was called Signed-off-by: NPhilipp Reisner <philipp.reisner@linbit.com> Signed-off-by: NLars Ellenberg <lars.ellenberg@linbit.com>

After disconnect (most likely mdev->net_cnt == 0) and we are still in an unstable state (!drbd_state_is_stable()). When we get an IO request in drbd_get_max_buffers() (called from __inc_ap_bio_cond(), called from inc_ap_bio()) we wake up misc_wait. Misc_wait is also used in inc_ap_bio() to sleep until the outcome of __inc_ap_bio_cond() changes. => Busy loop! Solution: Have a dedicated wait queue for get_net_conf() and put_net_conf().

When a fencing policy of "resource-and-stonith" is configured, and DRBD looses connection to it's peer, we can delay the creation of a new current-UUID until IO gets thawed. That allows one to deploy fence-peer handlers that actually commit suicide on the machine they get started.

Since we can not thaw the transfer log, the next logical step is to allow reconnects while the fence-peer handler runs. Signed-off-by: NPhilipp Reisner <philipp.reisner@linbit.com> Signed-off-by: NLars Ellenberg <lars.ellenberg@linbit.com>

Pretty straight forward conversion. Note that we do round-robin between the drives that have available requests, before we simply used the drive that the IO scheduler told us to. Since the IO scheduler doesn't care about multiple devices per queue, the resulting sort would not have made sense. Fixed by Vivek to get rid of a double lock problem in set_next_request() Signed-off-by: NJens Axboe <jaxboe@fusionio.com> Signed-off-by: NVivek Goyal <vgoyal@redhat.com>
