drbd: don't expose failed local READ to upper layers
fix regression introduced in 8.3.3: commit a9b17323f2875f5d9b132c2b476a750bf44b10c7 Author: Lars Ellenberg <lars.ellenberg@linbit.com> Date: Wed Aug 12 15:18:33 2009 +0200 out-of-spinlock completion of master bio : (bio_rw(bio) == READA) ? read_completed_with_error : read_ahead_completed_with_error; is obviously not what was intended. No one noticed because of * page-cache at work, * local RAIDs Impact: Failed local READs are not retried remotely, but errored to upper layers, causing filesystems to remount read-only, or worse.
