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.
