Lars Ellenberg 1d53f09e17 drbd: fix potential kernel BUG (NULL deref) ... BUG trace would look like: lc_find drbd_rs_complete_io got_OVResult drbd_asender Could be triggered by explicit, or IO-error policy based, detach during online-verify. We may only dereference mdev->resync, if we first get_ldev(), as the disk may break any time, causing mdev->resync to disappear once all ldev references have been returned. Already in flight online-verify requests or replies may still come in, which we then need to ignore.
